The next major release of VMware Fusion isn’t due for some weeks yet, and the current version doesn’t seem to get on well with Catalina beta. At the moment, there isn’t really a choice, because of their different development cycles. I’m fortunate in having old versions of both Parallels Desktop and VMware Fusion to choose from.
SHOULD I UPGRADE MY MAC FROM 10.9.5 TO UPGRADE
Although this will be for my iMac Pro, when I upgrade that in due course, I’m going to run a full dress rehearsal on the MacBook Pro in Catalina beta first.įor this, I need two key components: the virtualisation environment, and a copy of the macOS 10.14.6 installer app. What I do need to prepare next is my virtualised copy of Mojave, in which I will keep key 32-bit apps running in the future, rather than continuing to dual-boot the MacBook Pro. If anything goes seriously wrong, I can afford to live without it for a few days whilst I unscramble it. It’s a 13-inch 2017 model without a Touch Bar, so lacks a T2 chip, and its internal and external SSDs aren’t encrypted either. It has hardly any 32-bit software, doesn’t ever get backed up, and is normally the sacrifical lamb for anything new. The MacBook Pro which I’ve been dual-booting between Mojave and Catalina beta will be upgraded as soon as it can download the first release. In particular, that means access to its existing Time Machine backups.
At present, my main working system, an iMac Pro, is running Mojave very happily, and won’t be upgraded on the day of Catalina’s release, but later, when I’m confident that I’m not going to lose anything important by upgrading. The first decision was when to upgrade each of my two Macs, which is dictated by a combination of requirements.
I’m now well into planning for my upgrades to Catalina.
