Dosdude1 Patcher El Capitan. Oct 05, 2019 Let's say I want to install Catalina on an old iMac 7,1 (with SSE 4.1 support) to which dosdude1's APFS ROM Patcher has been previously applied. The iMac is currently running El Capitan, but I want to completely erase its disk and reformat it as APFS. This is how to install Mac OS X 10.11 'El Capitan' on an unsupported Mac Pro. In this video, I use a Mac Pro 1,1 (that has been flashed to 2,1 firmware). In this video, I go over the process of installing macOS High Sierra on an unsupported Mac. This process involves the use of 'macOS High Sierra Patcher', whi. Search: Dosdude Catalina Patcher. If you are search for Dosdude Catalina Patcher, simply cheking out our info below. Mac OS X El Capitan can be downloaded directly from the Apple website. The Beta version of the OS is available but the final version will be made available towards the Autumn season of 2015 as speculated by many Apple users.

High Sierra Patcher Dosdude1

Off the top, I want to thank dosdude1.com for providing the software – and the instructions – to upgrade many older Macs to OSX Sierra. Please donate if you can!

The benefit to this update is that we are getting a number of Macs – Towers, Mini’s and iMacs – that can only go up to OS7 or OS8 and thus are increasingly out-of-date. If we can get at least some of these Macs up to OSX Sierra, we have a great chance to give them new life for a few more years. And that means we can give students, families, non-profit groups and others the ability to work with the latest OS and be as productive as they can be going forward.

The website lays out the requirements, supported (and non-supported) machines, things you’ll need and known issues (which we laid out in Part 1.)

You can use the instructions from dosdude1 to take you through the process. My intent here is to give you my take as I went through those instructions.

TAKE ONE

The instructions are clear that you need a flash drive of at least 8 GB in size. I found that you can get away with a smaller one. That said, you will need to get ahold of a copy of the Sierra installer by using a newer Mac to get it from the App store or dosdude1 gives you a link to the MEGA Unlimited site in New Zealand – but you can get instructions on how to download it from other websites as well.

You’ll also need a hard drive with an older version of the Mac OS (based on the requirements for the upgrade) or a blank drive. In either case, you’ll be installing Sierra – so it will be a “normal” install as you would with any Mac update, or a clean install on a new or blank drive.

Update: This is my main drive info. I did this upgrade on an exact copy:

NOTE – we plan to do a clean install and, with some additional software tools (like Open Office) we will plan to make a Time Machine backup to use to make clones for other Macs. (Yes there are other ways to make clones – as in using SuperDuper or Carbon Copy Cleaner. But I’ve found that using a Time Machine backup is actually quicker. (See note below about this.)

We’ll write about that experience in a future blog.

TAKE TWO

Download the Patcher Tool as instructed. Plug in the USB drive and format it using Disk Utilities. (That said, the Patcher Tool will format it anyway when you go to the next step.)

NOTE – I used a 6 GB partition on a large USB drive that I have with various OSX installers without a problem.

It’s time to install OSX Sierra on the USB Drive. Make sure you know where the Sierra installer app is – the patch tool will want to know.

Run the Patcher Tool and click on the Sierra icon to verify your Sierra install app. This went as planned for me. Now it’s time to install the OSX Base System on the formatted USB drive (or in my case – partition).

Remember, this will be the boot drive from which you’ll install OSX Sierra onto the drive of your choice.

With the USB drive selected, I clicked on “Start Operation” to begin installing the Sierra install app.

This is where I ran into some trouble – as the install would get almost all the way to the end and then give me an error message. I reformatted the USB drive and tried again. Same thing. Third time, I LEFT what had been installed on the USB partition and walked away. The install was successful this time! Not sure why but it was time to move on.

TAKE THREE

I keep a Time Machine backup and a SuperDuper backup of my boot drive, so I decided to use the backup as the guinea pig for this update. I rebooted the Mac from the USB drive (Apple Menu -> Restart – Press the Option key). If your USB drive only has one partition (with the Sierra install on it) you’ll see your boot drive and one that is called “OS X Base System.” THAT is what you want to boot from.

I intended to UPDATE from El Capitan (10.11), but if you want to do a clean install, you’ll need to boot into the install drive and then pull down System Utilities to format that drive (yes – you could have done this before as well).

Proceed with the installation on the disk of your choice. This will take awhile so be sure to go into System Preferences and tell your Mac (using Energy Saver) to not go to sleep or turn off your hard drives.

Once installed, your Mac will boot into the new OS. You’ll know because the background will be the Sierra Nevada mountains and “About This Mac” from the Apple Menu will confirm it all.

TAKE FOUR

I was almost done! Although it LOOKS like you’ve upgraded properly, you still need to patch the new OS. So I rebooted BACK into the USB Sierra installer partition. This time, when it booted, I found a small box had popped up with four menu items. You only care about the last one – macOS Post Install. I chose that and it asks you to choose your Mac model.

Luckily – it TELLS YOU what Mac Model you have. Choose that model from the drop down box and you will see some suggested patches pre-populated for the model Mac you have. Select the drive you installed Sierra on and press PATCH. For some reason, I had to do this twice but it did finally take.

Dosdude1 Sierra Patch Tool Boxes

On the bottom of the Post Install, you’ll see “Complete!” on the left and a Reboot button. Ignore “Force Cache Rebuild.”

My Mac rebooted into the backup drive with Sierra installed. It worked perfectly! I checked for any updates and only had one – Pages – to update. The patched system should allow updates as well (at least for Sierra) but there have been none so far.

FINALLY

That was it! I will likely go ahead and install Sierra on my original El Capitan boot drive (2 TB) as well after giving Sierra a run through on the backup.

Given that the patches are Mac-specific, I’ll likely have to run the patcher tool on each machine we update at the MacRecycleClinic. The good news is, I can boot from the USB drive and install Sierra on any Mac that is supported. From there, I just have to run the Patcher Tool and choose the right version of the machine to patch.

The other plan (as mentioned above) – to create a Mac-specific Time Machine clone may not work but we’ll give it a try and report back. Redo hov1 lyrics english.

NOTE that there are still some restrictions with certain Macs – in some cases, for instance, WiFi won’t work – the website says machines ( a wide range actually) running the Broadcom BCM4321 WiFi module. The fix is to install a compatible WiFi card if one is available.

Let us know your own experiences with this patch and any suggestions you might have to make it easier.

Do you find macOS Mojave a bit too much and therefore want to downgrade? Is your Mac a bit slow or are you having problems with your apps? Or are you having some issues with your current macOS? Reinstalling macOS is often the last resort for fixing software issues on Mac.

This article will show the step-by-step process of how to clean install macOS on your Mac. Whether you need to download and clean install High Sierra, Sierra, El Capitan, Yosemite, or an earlier version of OS X, this guide got you covered. We’ll start by showing you how to clean install macOS Mojave, the latest version of macOS, before moving on the more complicated business of installing an earlier version of macOS or OS X.

If your Mac is too old to install macOS Mojave, you can still upgrade to the latest version of macOS that is compatible with it, even if you can't find those versions of macOS in the Mac App Store. Apple has pages for High Sierra, Sierra and El Capitan than include links directly to the hidden Mac App Store pages with those downloads.

1. In this video, I go over the process of installing macOS High Sierra on an unsupported Mac. This process involves the use of 'macOS High Sierra Patcher', whi.
2. Things you'll need: - A copy of the macOS High Sierra Installer App. This can be obtained from the Mac App Store using a machine that supports High Sierra, or by using the built-in downloading feature of the tool. In the Menu Bar, simply select 'Tools Download macOS High Sierra.'

What You Will Need

/autocad-dwg-viewer-free-download-for-mac/. To reinstall macOS, you need a removable flash drive with at least 15GB of free storage to make a bootable USB on Mac. This is where you’ll save the installer file for your preferred version of macOS. Make sure that there is no important data on the drive because we’re going to erase it for this purpose.

Another thing you need to take care of before reinstalling your macOS is your backup. In case something goes wrong, at least you saved your important data. When backing up your files, clean out your junk first by using an app such as Tweakbit MacRepair. It deletes all the unnecessary files so you don’t have to carry them over to your freshly installed macOS.

To create a backup of your data using Time Machine, follow these steps:

• Connect an external hard disk to your Mac using a USB cable, FireWire or Thunderbolt cable.
• Click the Apple icon located in the top left corner of your screen.
• Choose System Preferences > Time Machine.
• Turn on Time Machine by moving the slider to On.
• Click Select Backup Disk and choose the external drive you want to use for your backup.
• The external drive will be formatted, and the backup process will start in a few minutes.

Downloading and reinstalling your macOS is a simple process, but take note that every time you make important changes to your Mac, you risk problems that may cause you to lose your data. So before you do anything else, make sure your data is secured. It’s better to be safe than sorry.

Once you have your USB drive and backup taken care of, then you’re ready to clean install your new macOS.

Step 1: Format the USB drive.

You need to re-download the installer file for your chosen macOS and save it on your USB flash drive. So the first thing you need to do is format the drive as a Mac OS Extended (Journaled) volume with a GUID Partition Table. Make sure there are no important files or data on the drive because everything will be erased.

To format your drive, follow these steps:

• Head to Applications > Utilities > Disk Utility.
• Choose your USB drive and click Erase.
• Rename your USB Drive to Untitled.
• Choose Mac OS Extended (Journaled) as the format type. For Macs running High Sierra or Mojave, choose APFS from the options.
• Select GUID Partition Map under the Scheme options.
• Click Erase. This may take a couple of minutes, depending on how big your flash storage is.
• Click Done.

Step 2: Re-download your chosen macOS installer file.

If you’re re-installing Mojave, all you need to do is search for it at the Mac App Store. Just click Download or Get, depending on the Mac App Store version you are using. If you get a warning message saying that this version of macOS is already installed on your computer and asking whether you want to continue, just hit Continue. Type in your Apple ID and password to proceed. The installer is a big file, so downloading it might take some time. macOS Mojave, for instance, is around 5.7GB.

Once the installer file has finished downloading, it will automatically launch. We don’t want it to run yet, so hit Command + Q to quit the installer.

Getting the installer file for older versions of macOS requires more work because Apple doesn’t offer downloads of old macOS versions on the Mac App Store, even if you search for them.

If you’re running macOS Mojave, you won’t be able to find older versions of macOS on your App Store no matter what you do. You need to find a computer running an older version of macOS and download the installer file from there. You can find the older macOS and OS X versions under the Purchased tab of the Mac App Store. You’ll be able to download these versions of macOS and OS X from here:

• OS X El Capitan
• OS X Yosemite
• OS X Mavericks
• OS X Mountain Lion
• OS X Lion

You’ll notice that Sierra and High Sierra are not included in this list, and that’s because Apple removed Sierra from the Purchased list when it introduced High Sierra in 2017. Fortunately, you can still download Sierra from this link as long as you’re using a non-Mojave Mac.

If you want to download High Sierra, you’ll have to download it from another computer that’s running an older version of macOS and copy it from there.

Step 3: Create a bootable USB on Mac.

The next step is to create a bootable USB disk that you will use to install a fresh copy of your macOS. You need to install macOS from USB, so you need to create a bootable drive, using the Terminal.

To make a bootable macOS install drive, follow these instructions:

• Launch Terminal by pressing Command + Space and typing Terminal in Spotlight. Or you can go to Finder > Go > Utilities > Terminal.
• Connect the formatted USB drive to your computer. Make sure the name of the drive is ‘Untitled’ for this to work. Rename the drive if necessary.
• Copy and paste this command into the Terminal:

sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled — /Applications/Install macOS Mojave.app

• Hit Return.
• Type in your password.
• This process can take a while, so be patient. When you see the word Done, this means that the bootable drive has been created.

Step 4: Install macOS from USB.

Now that your installer is ready, it’s time to install a fresh copy of your chosen macOS, using your installer drive. Follow these steps to reinstall macOS from your USB drive:

Connect your bootable drive to your Mac, then turn on your Mac or restart while holding down the Alt or Option button. This will open up the Startup Manager.

Choose to install your macOS from the external drive.

Click Disk Utility, choose your Mac’s hard drive, then hit Erase.

Go back to Startup Manager and click Install macOS.

This process will install your chosen macOS on your computer. Take note that all apps and data will be deleted from your Mac, so make sure that you have a backup of your files. The installation might take some time, so just wait.

Once the installation is finished, you can restore your apps, files and settings from your backup. Or if you want everything to be as good as new, download your apps again manually. This is recommended if you were having issues with your apps in your previous macOS.

While the yearly major macOS update system is free to install, it is still limited to Macs that Apple deems compatible, and every year a generation of Macs essentially becomes obsolete. This is despite the fact that Apple is eager to emphasize that macOS is a widely compatible operating system.

As it happens, there are still people with close to ten-year-old Apple desktop computers still in use on a daily basis, likely performing a range of lighter tasks.

Which Macs Don't Support High Sierra

For some reason Apple doesn't want to allow these Macs to run its latest operating system, currently macOS 10.13 High Sierra. This leaves the following Macs on macOS 10.11 El Capitan:

• MacBook Pro – late-2009 or earlier models
• MacBook – late-2008 or earlier models
• MacBook Air – 2009 or earlier models
• iMac – late-2008 or earlier models
• Mac Mini – 2009 or earlier models
• Mac Pro – 2009 or earlier models.

These machines are considered obsolete and vintage by Apple. The company defines vintage products as those that have not been manufactured for more than five years but less than seven years ago. Obsolete products are those discontinued more than seven years ago.

How to Install macOS High Sierra on Unsupported Macs

Though Apple doesn't support the above hardware officially, someone has thought about sharing the love for these older machines. A developer known as DOSDude1 has written a patch that works on Macs with the Penryn architecture. Using this still imposes certain limitations, but at least makes it possible to install macOS High Sierra on the following Macs:

• Early-2008 or newer Mac Pro, iMac, or MacBook Pro (MacPro 3,1 and 4,1, iMac 8,1 and 9,1, MacBook Pro 4,1, 5,1, 5,2, 5,3, 5,4, and 5,5).
• Late-2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBook Air 2,1, MacBook 5,1).
• Early-2009 or newer Mac Mini or white MacBook (Mac Mini 3,1, MacBook 5,2)
• Early-2008 or newer Xserve (Xserve 2,1, Xserve 3,1).

If you happen to own any of the Penryn Macs mentioned above, the macOS High Sierra Patch Tool written by DOSDude1 will make running the latest software possible. But remember, with High Sierra you will also migrate to the Apple File System, and it is highly recommended that you first disable SIP because it may prevent the patch from working at all.

Installing the operating system on any of these Macs will require some technical knowledge, so it is not recommended for novice users. Also, a backup of your data is always a good idea in case anything goes wrong.

While there is a full step-by-step tutorial and video tutorial available on DOSDude1's website, it’s good to get a summary of the basics, which start with downloading the macOS High Sierra Installer app from the Mac App Store:

1. Format a USB drive as Mac OS Extended (Journaled) via Disk Utility.
2. Open the macOS High Sierra Patcher tool, navigate to the High Sierra Installer App, then select your pen drive and click “Start Operation”.
3. Boot from the USB drive by holding down the option key after reboot.
4. Install macOS normally, reboot back on the installer drive, and then open the “macOS Post Install” application.
5. From the options, select the Mac model you own. This step is important, because it contains the optimal patch for that specific model.
6. Click the “Patch” button, and after the process has finished, click “Reboot”.

The Reason Not To Install macOS High Sierra on an Unsupported Mac

As you may have already experienced with other types of officially unsupported machines, the probability of having issues is much higher. The same applies in this case, too, since the macOS High Sierra Patcher will render your iMac 8.1 Broadcom Wi-Fi chip useless for certain models.

Macs that use the Broadcom BCM4321 Wi-Fi module will not have functional Wi-Fi when running High Sierra. Another issue that has been highlighted by the developer is that the trackpad in the MacBook 5,2 isn't fully supported in this version of OS.

Dosdude2

These are just a few of the possible issues that could arise, and this is before even mentioning the various potential software errors that you can run into by using out-of-date hardware. Without getting the proper knowledge beforehand, you'll need to revert back to the previous state of the Mac, which won't be an easy process, especially not without a Time Machine backup.
