Wish to delete dual boot Mac OS (is it an easy process?)

[Logic_4.8]

 

LPX: 10.8.1

 

iMac Retina 5k, 27-inch, 2019 (1TB SSD)

Processor: 3.6 GHz 8-Core Intel Core i9

Graphics: Radeon Pro 580X 8 GB

Memory: 64 GB 2667 MHz DDR4

MacOs Ventura 13.6.4

 

External memory: 1TB Samsung X5

 

Hi, I don’t know if this is the right place to post this question:

 

I have a dual / Quad? boot (well actually I have Mojave, Catalina, Big Sur, Ventura) on  my iMac.

 

I wish to delete “Catalina & Big Sur” - but leave “Ventura & Mojave”.  I wish to keep Mojave BECAUSE I have some very useful 32bit Mixing-Desks (and other personal reasons), that are still fully operational on Mojave.

 

Is it an easy process to delete - because I want to “free-up” memory on my internal SSD

 

Basically, I want to keep “Ventura & Mojave” & DELETE “Catalina & Big Sur”

 

Also, I may now be tempted to upgrade to Sonoma 14.3.1, after reading that this Mac OS completely solved the flashing Project Window in Logic Pro 10.8.1.

 

Thanks

Forgot to include the current LPX version I am using.

Assuming you have four partitions on your internal SSD, you can use Disk Utility from /Applications/Utilities/Disk\ Utility.app. Open up Disk Utility and reformat your Catalina and Big Sur partitions obviously taking care that you are formatting the partitions that you don't want. There are plenty of YT videos that explain this process in detail.

Hey there... thanks for that.  I thought that there may have been some complications in regard to the Mac OS's - and that is why I thought I'd check here first.
