The presented at WWDC21 Mac operating system macOS 12 Monterey brings new functions and a revised look to Apple computers, such as the Mac, iMac, Mac mini and MacBook models from Air to Pro.

Free up Mac memory for the macOS upgrade: Here's how!

Do you use one older Mac compatible with Monterey and which has little storage space left by storing various documents, apps, photos, music albums and the like, there are several options for cleaning up. You can delete duplicate files and apps that are no longer used with the linked files and system folders by using CleanMyMac X (here the website). The cleanup tool for Mac also offers the ability to clean up photos, email attachments, iTunes junk and more. Especially when it comes to apps, photos, videos, music and the like, a few gigabytes quickly accumulate that can be cleaned up.

Another way to free up storage space for the Mac upgrade to macOS Monterey with 20 GB of free storage as a recommendation is to store documents, pictures, videos, music and the like. Large hard drives to which you can move entire holiday albums, music collections and film archives can be found, for example, with the WD hard drives My Book, My Passport, My Passport Ultra and Elements. You can find out what makes the difference here: Difference between WD My Book, WD My Passport, WD My Passport Ultra, and WD Elements. A large hard drive will also help you make a backup before upgrading to Monterey. Don't forget the backup for me!

    According to Michael Tsai, BS and Monterey need at least 50 GB of free disk space to install new versions. This is real disk space and not the value you see in the Finder. macOS creates TimeMachine snapshots there (even if no TimeMachine is used on the computer). There are also downloads and other junk.

    With DaisyDisk and similar programs this should be deleted before an installation. According to DaisyDisk, I have 70 GB of garbage on the disk again.

    Incidentally, the issue of free disk space affects the small bug fix releases, because they have always brought macOS with them since OS. For security or something.

    CleanMyMac is overpriced and doesn't do much more than I can do by hand.

    The blog told me that I am typing too fast. Head on desk!

      Hi Beatrix! You type too fast for spam detection ... only a bot can type that fast. 😂 And yes, I think CMM is nothing for you ... but for many users who just want to press buttons, the tool is quite helpful. It also snaps out half-finished local backups of iPhone and iPad etc ... as a rule, no normal user answers. I have Setapp anyway and it comes with it, which is very convenient.
