They added support for virtual reality headsets as well.īesides that, when it comes to Safari, Mac search engine, there are some notable improvements with the update. These formats compress data - that’s a benefit as files can get huge with ever-rising resolutions. Thus, it boosts performance and helps manage device memory issues.Īpple also introduced new formats for video and photos in this version. It enables the storage and encryption of a large number of files.

The Apple file system is the most significant feature it brought. There are few bells and whistles, but the changes are noticeable and positive. High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. I am using a Late 2014 mac mini refurbished in 2017 with, again, Monterey.In essence, High Sierra took what was good with Sierra and developed it into a more comprehensive software. So I want to know if anyone has been able to successfully do this.

Should I reset PRAM and what will that do to affect the process?.

Will having had Monterey do something to make that not work?.

Then just hope it falls back on Sierra and it actually works, and press on from there.īut there's 2 questions I have with this: So theoretically what might work I guess is to just boot into recovery, erase drive, and rather than reinstalling, reboot again, and perhaps use cmd-alt-P-R. More than this, I would prefer to have the option to run a pre-Catalina release.

Which is what I then did in normal recovery mode, then I tried to reboot into the USB. However, once I tried to go through it, the disk was locked. I tried the third method, but what ended up happening once I booted into that, was that it went into recovery mode, and the option to install macOS was showing the high sierra icon. 1 was to boot into recovery and reinstall (clearly they might have meant erase disk and then restart recovery before reinstalling), 2 is to use time machine, so doesn't apply as I don't use it, and 3 was to create a bootable install USB. I saw an article with 3 ways to downgrade. My plan was to back up everything I wanted to keep (desktop, documents, library, etc), start from a clean slate (which would probably make it run faster anyway), create another volume, and install Catalina as well (just so I'd have dark mode and a 64-bit only OS), and restore from there.

For example, I do have one game that doesn't work, which is also a legacy app. If I wanted to do anything that would not work in Mojave.If I were to get an eGPU at some point, I might want to test out with older Blender versions before they dropped graphics options, as Apple dropped support for OpenGL in Mojave.OK, so I just tried to install High Sierra for a couple reasons:
