I use Parallels 12 and the latest upgrade of Windows 10. I cannot find the option to increase RAM or change number of cores any more.
Hi @Bibi Fricotin , please check if you have lock symbol at the bottom left of the Window . Please click on it and enter your Mac admin password to make the changes.
Nowhere with the machine shut down and the padlock unlocked do I have the option to change the amount of RAM or number of core I tried General, Options and Hardware and couldn't find it.
