We're in the middle of an architecture migration and it's pretty messy. You would do very well to nurse another couple of years out of your Classic Mac Pro as not Big Sur nor Monterey nor M1 Macs are particularly stable right now. I have a 2009 now with dual X5675 processors (lower power and quieter than either an X5680 or X5690 under a dual CPU heat sink, X5690 is fine in single CPU CMP), with 96 GB of RAM and a Radeon VII running just fine under both 10.14.6 and 11.6.1 (never installed Catalina and still prefer 10.14.6, not sure I'll use 11.6 with this computer). You also need to have the right generation of Xeon processor (you probably already have the right one). What's important is to upgrade the firmware from 4,1 firmware to 5,1 firmware. I have good news for you It's quite possible to upgrade a Classic Mac Pro to 10.14.6. This is just akin to using a big hammer to fix.If that's also a machine from 2010, your maximum OS is macOS 10.13.6. You definitely should not need to re-install the OS or OS updates. Signing out and back in isn't too much of a headache, unless you have a lot of data, with regard to your bandwidth, in which case it qualifies as a major PITA. That said, 10.13.4 seemed to cure a several year long problem I had with syncing the Keychain to one specific device (although I have had problems with other devices in the past). overnight) then signing back in one by one. Clicking the 'Sync Now' button on the Mac hasn't helped.Īnnoyingly, the only fix for iCloud problems in my experience, seems to be signing out on ALL devices/Macs. There are messages *after* it that have synced (messages in the same message thread, i.e. There were no major feature changes discovered during the course of. Today however, I note that a message I sent yesterday, mixed somewhat between the iPhone and iPad, which included an image from both, has not synced onto the Mac. The 10.14.2 update introduces performance improvements and bug fixes for issues that weren't addressed in macOS Mojave 10.14.1. I did the same when the MacOS update was available and activated it via Messages preferences and it synced perfectly. My guess is that Apple are doing stuff at their end.įWIW, I installed successfully and activated Messages in iCloud on an iPad and an iPhone and it worked fine.
