But if you have 25 GB of free space available, you should be able to successfully perform an install of Catalina.

It’s difficult to estimate the size of the free space you’ll need since it’s dependent on the version of the Mac OS you’re running before the upgrade.

If you’re performing an upgrade install, you need to make sure the startup drive has enough free space for the installer download (6.5 GB), as well as room for the files the installer will copy to the startup drive during installation. I normally suggest a good deal more free space than that, but here we’re just talking about a minimum to ensure you can install and use macOS Catalina. As if that weren’t enough, you should keep at least 10 to15 percent of the startup drive free to ensure adequate performance. In addition, you need to allow for space for your user data, applications, and future updates.
You can see how much free space is available on the target drive by highlighting the drive and pressing Command-IĪ clean install uses up around 20 GB of storage space. After that, the amount of space needed is dependent on the type of installation you’re performing: a clean install or an upgrade install. Storage Space: You’ll need about 6.5 GB of space just to download the macOS Catalina installer.
The CPU temperature will also stay in this healthy temperature range.ĭownload Macs Fan Control on the dev's website, on github, or from my local mirror (v4.1.12).Installing a new version of the Mac OS is generally a fairly pain-free process this trend continues with macOS Catalina. So since we need to make sure the PSU does not overheat and melt your display panels LED strips on the right side, we set the CPU fan speed in relation to the PSU temperature. I learned that Apple did decide to "cool" the PSU by blowing the CPUs hot air onto it. Set the CPU fan to be controlled by the PSU Primary temperature. This stuff is sitting in the middle of the iMac case. If your disk runs hotter, you'll shorten its lifetime and jeopardize your data. 40☌ – 75☌ (this controls the right hand side of the iMac) The HDD fan is controlled by the HDD temperature.

Here's my settings: Set everything to manual ODD Fan is controlled by GPU Diode. So I decided to set up the fans manually, the Mac now runs much cooler and still it's not too loud. Macs Fan Control indicated that the PSU was running on 70☌ and more, and something made a buzzing sound (like a wire dangling inside a fan, which was not the case). Yesterday I encountered a customers iMac which ran crazy hot on the backside.
