There’s a brand new version ( Little Snitch 5) made specifically for Big Sur, but so far it’s crashing on my system.Īrq backups - give me errors but they are probably to do with new permissions to be enabled rather than macOS incompatibilities. Little Snitch - this flexible and intelligent software is my go-to when it comes to controlling what network connections I allow my Macs and Macbooks to accept and initiate. SuperDuper! backup software is not Big Sur ready just yet - apparently there was no way to create a bootable backup copy at all - even using native macOS methods Most of the apps work just fine for me, but some of the most advanced tools are having issues: This may be one of the reasons why Big Sur feels much quicker than Catalina, even though it was an in-place upgrade and not a fresh install. My upgrade process resulted in some security permissions that must be re-created, meaning many extensions are not running or not running with the desired access to network or filesystems. Some apps like Tower have new versions released just in time for Big Sur and benefit from seamless integration both design and functionality wise. Not very clear if it’s just the appearances or deeper upgrades of the daily apps. Pretty cool changes to the interface make most of things and apps look fresh and new. It doesn’t look to be anything like app blocking just yet, but privacy concerns are real enough to think twice before upgrading to Big Sure - apparently you can’t easily disable trustd/OCSP there. I assumed it’s some weird local hostname/DNS dependency I introduced myself - but it seems related to OCSP and trustd daemon.īig Sur launch caused slowdown on Apple infrastructure and this made the scale of this issue apparent: every app launch must dial back into Apple servers before it proceeds with the start. Even on Catalina I noticed how until my desktop/laptop connects to network, a lot of apps from startup list won’t work. Jeffrey Paul wrote an excellent article on the day of Big Sur release: Your Computer Isn’t Yours. I’ve yet to go through the in-depth reviews but wanted to share first impressions. Apple released the next macOS version on November 12, codenamed Big Sur.
