Bugs detected in the latest macOS 10.15.5 update — 2022

Just a few days ago macOS 10.15.5, the latest version of the operating system for Macs, was released. Luckily, this version corrected some tedious errors detected in previous versions, but ironically it has brought some new ones that can cause more than one headache to users.

Bugs with backups on macOS 10.15.5

APFS Apple File System

There are several ways tobackup a macand one of them is through third-party applications such as Carbon Copy Cloner. Precisely Mike Boombich, creator of this tool, recently warned that the latest version of macOS has a bug when making backups usingAPFS, the Apple file system. She explained it all in a detailed article on his personal blog.



According to this report, an error appears when scheduling computer backups through the aforementioned Carbon Copy Cleaner program, which is done through a boot disk. Yes indeed, the fault is not detectable with the naked eye , since the process appears to be apparently correct. This is how Boombich explained it:

The chflags system call can no longer set the SF_FIRMLINK flag on a folder on an APFS volume. Instead of failing with an error code that we would have caught, it fails silently: it exits with a successful status, but silently fails to set the special flag. That's a bug in the APFS file system implementation of chflags: if a system call doesn't do what you ask, it's supposed to return an error code, not a success.

It has also been possible to verify that this bug is only present in this version, since in macOS 10.15.4 and earlier the process can be carried out successfully. The solution to this problem for users using this tool is detailed in the aforementioned Boombich article, which you can access at the source of this article.

Problems updating macOS

macOS download error

Another error that some users are reporting is that some Error message during the macOS 10.15.5 download process. In fact, we ourselves have been able to experience a connection problem in the first person when carrying out this process. In our case, despite having a good connection, we were able to solve it by connecting to another WiFi network. The rest of the failures could be due to the saturation of Apple's servers, so only patience could be a solution. However, if you experience this error you could try restarting the Mac and the router.

macOS 10.15.6 in sight?

We are very close to WWDC 2020, which will be held virtually on June 22 due to the COVID-19 pandemic. This event will present new operating systems that will enter beta until September or October. However, during this time we could also see some update for all users as far as current systems are concerned.

In macOS no more bugs have been detected at the moment apart from what was mentioned above, but it is clear that the company will have to provide a solution. It remains to be seen if these corrections can be made by some alternative means to a new software version, but in any case, it should not surprise us that macOS 10.15.6 will arrive in the coming weeks.
