![]() It could be a botched backup migration but twice now I’ve had app and service lockups permeate throughout the system and apps that required a reboot to stop I just got a new 13” MBP and sold my 2015 Pro that was on Mojave. Mac App Notarization and Customer Privacy.Notarizing Command-Line Tools for macOS 10.15.Chrome Updater Bug Prevents Macs From Booting.How My Application Ran Away and Called Home From Redmond. ![]() Any feature that requires phoning home to Cupertino is going to be very fast in Cupertino, but possibly very slow elsewhere. This is why Apple needs remote workers, not just in the US but worldwide. The random stalls and slowness are pervasive, infuriating, annoying, and perhaps even approaching demoralizing. The macOS security team needs to ask themselves hard questions about their implementation choices when very smart people are disabling huge parts of their OS security layer just to get reasonable performance from common tasks.Īpple needs to do something about this. The good news: after re-enabling the plug-in, it once again launches at normal speed (until days or weeks later when FSEvents gets bogged down again). Nevertheless, users find that disabling the plug-in fixes the problem and conclude that the plug-in was at fault. This happens before it has actually started loading the plug-in, so it’s not actually related to what the plug-in does. The new (since Mojave) secure Mail plug-in loader sometimes blocks for up to a minute waiting for FSEvents to flush, causing Mail to get stuck at launch. The API to access the system Contacts database unpredictably freezes for 10 seconds or so. I just take a little break until it unfreezes. Now this happens so often that I don’t even bother checking the keyboard. If the mouse was frozen, you had to reboot the Mac. In the old days, this never happened, so one didn’t even need to check whether the Mac responded to the keyboard. Sometimes the mouse stops responding (and the cursor stops animating) for 5–10 seconds. ![]() ![]() It takes at least 3 seconds-with a spinning beachball-to auto-fill a login in Safari. The system is almost unusable, as seemingly every app is waiting on something that’s waiting on those processes. If this happens after a reboot, when lots of applications are being relaunched, those processes max out the CPU for minutes. Activity Monitor shows that the system is doing some sort of privacy check and waiting on the tccd or lsd process. It’s worse in Catalina, but I’ve been seeing frequent problems since Mojave:Īpplications, particularly OmniOutliner, often freeze for 30–60 seconds or so when opening a document. With SIP enabled and on a bad internet day I can have the entire machine freeze for 1-2 seconds every 10th minute, not to mention everything just being sluggish. This is the worst issue, sometimes, things will stall for 5-30 seconds. Specifically calling SecKeychainFindGenericPassword can cause noticeable delays, on a bad internet day I had this call stall for 3.3 seconds and this was with System Integrity Protection disabled! Surprisingly though, just obtaining the display name or icon for one of these folders will trigger Apple’s code to verify that the client is allowed to access the location. So even if you write a one line shell script and run it in a terminal, you will get a delay! This is not just for files downloaded from the internet, nor is it only when you launch them via Finder, this is everything. This check for me takes close to a second. I say reduce, because I still do get some delays even with SIP disabled, but the system does overall feel much faster, and I would strongly recommend anyone who thinks their system is sluggish to do the same.Īpple delays execution while waiting for a reply from their server. In episode 379 of ATP both Marco Arment and John Siracusa described noticeable delays and stalls after upgrading to macOS 10.15.Īnother way to reduce the delays is by disabling System Integrity Protection.
