MacOS patcher (discontinued)More advanced users may consider using macOS Patcher, which is a command line-based tool that provides the same hardware support, while also adding support for MacBook4,1 systems. The installation guide can be found here and an installation guide video here. It contains all the patches necessary to achieve the hardware support listed above. Installation macOS Catalina PatcherTo install on your machine, you can download and run macOS Catalina Patcher application, which will let you download a copy of the latest installer app from Apple and create a bootable installer drive for use on unsupported Macs. Pre-Metal Intel video cards (Intel HD Graphics 3000 and Intel HD Graphics Arrandale) Pre-Metal Nvidia video cards (GeForce 5xx series and older without acceleration, GeForce 3xx Series and older with acceleration i.e. Video Card SupportPre-Metal AMD video cards (Radeon HD 6xxx series and older without acceleration, Radeon HD 4xxx series and older with acceleration.) Searching for older Macs breaks the connection either on the 2011 MacBook or the 2013 iMac which I patched to search for older Macs. So its a one way street unfortunately as the iPhone and 2013 iMac will not see the 2011 MacBook even when setting the 2013 iMac to search for older Macs, but hey something is better than nothing.ĭouble Edit: Actually airdrop on the 2011 MacBook relies on both the iPhone and iMac to be both on, it seems that the iPhone to iMac handshake activates the MacBook handshake so in order to airdrop in a one way direction to either the iPhone and/or iMac all 3 devices need to be on and logged in so to speak. Its like the iPhone acts as a catalyst to force the MacBook to respond to airdrop, when I lock the iPhone the airdrop to iMac will stay persistent for a minute. Now I can airdrop from MacBook to iPhone and to a newer iMac but only when I unlock my iPhone. After install I could not get any system to see or be seen by the 2011 MacBook 8.2, after applying all of jackluke's patches still the 2011 MacBook would not show up anywhere, I went back to the post install patches and disabled wifi legacy patch and enabled BCM4231 wifi support patch. I can hardly notice any difference between HS and Catalina on this Mac, mind you I only tried Netflix, YouTube, and google/word type apps so far.ĮDIT: I found an interesting scenario to do with airdrop. For older macOS versions (like Mojave and Catalina), patchers provided by dosdude1 might be a better choice.Considering that all reports seem to indicate that Catalina will run terribly on a MacBook early 2011 8.2 with a working non disabled 6750m because of hardware acceleration issues Im left scratching my head because it seems to be working fine for me. It's an all-in-one tool allowing you to download, install, patch, and hopefully boot macOS on your target machine. The patcher we've used in this guide is the OpenCore Legacy Patcher. You may take a hit in terms of performance, you may need to leave System Integrity Protection in a lowered state (or disable it altogether), and the process may take much longer than expected. You'll need to download an installer, create a bootable USB drive, patch the drive to enable support for your Mac, and see the installation process through. ![]() Installing an unsupported version of macOS on your Mac takes a decent amount of work the process is more involved than the usual macOS installation upgrade process. ![]() Here's how to do it and some things to keep in mind if you go this route. Has Apple ended support for your Mac? You can install new versions of macOS anyway by creating your own patched installed.
