Re: MPLAB X v5.45 compatibility with Mac OS Big Sur
On my iMac running Big Sur, MPLAB X IDE v5.45 runs fine, so far it never crashes. In the earlier MacOS Mojave, the only problem I have with MPLAB X is that it crashed quite frequently during start up. I suspect it was due to the Java run time also being used by Safari. My workaround was to close Safari, wait a while, close one or two other programs (that are not important), then launch MPLAB X again. Usually MPLAB X will be able to launch successfully after this. Then I can re-launch Safari. But this workaround may not work 100% of the time. The sure work way is to log-out and log-in of MacOS (Mojave).
I didn't upgrade to Catalina, and went straight to Big Sur. MPLAB X IDE v5.45 seems to be far more stable in Big Sur!
