Note: this article is no longer being updated, and doesn’t cover 10.14.2 or later. To see the list of bugs in 10.14.6, which is being maintained, please go to this article.
This article lists bugs which you and I have encountered in macOS Mojave 10.14.1 itself, rather than issues in specific third-party applications and other software.
iCloud Drive document sharing – versions erratic and unreliable
Thanks to Edoardo for first drawing my attention to this.
ssh – doesn’t conform to privacy setting rules
ssh works with Mojave’s privacy settings, it breaks their rules:
- Unlike all other apps and tools, when it is not in the Full Disk Access list, it is given full disk access.
- Unlike all other apps and tools, when you remove it from the Full Disk Access list, it is given full disk access.
- Its access to protected data is controlled by an oddly-named stub, not
- Its behaviour is not documented anywhere by Apple.
Full details are here. Apple is understood to be working on improving this for a future update to Mojave.
System Information – Legacy Software wrong and misleading
EFI version numbers – System Information and
eficheck return different numbers
In 10.14.1, the EFI firmware version number returned in System Information has the form
188.8.131.52.0, but that returned by
eficheck commands such as
/usr/libexec/firmwarecheckers/eficheck/eficheck --integrity-check are different in form and content, e.g.
Privacy protection – malicious apps can discover which apps have Full Disk Access
I gather that another bug has been discovered in the new enhanced privacy protection, in which a crafted app can obtain a list of those apps which have been given Full Disk Access in the Privacy section of the Security & Privacy pane. Apple has been informed, and a fix is expected in a future update to Mojave.
In itself, that information is of little use, but could be exploited by malware to ride on the back of an app which already has this access.
(Thanks to security researcher Phil Stokes at Sqwarq for this information.)
App Store – removes some recent updates once installed
Although not a major functional issue, this makes the list of recent updates completely unreliable.
App Store – search returns weird hits
When you enter some search terms into the App Store app, completely unrelated apps appear in the results. In some cases, these are additional to genuine hits, in others they just appear weird and unrelated. For example, searching on the word
consommé (a type of soup) consistently returns an app which has nothing whatsoever to do with the word, nor does it appear in the info provided about the app.
clover returns three genuine hits, and three spurious apps which are completely unrelated. This looks like the store’s metadata are corrupted with random terms.
Dark Mode – QuickLook and other bugs
Thanks to Artyom for drawing my attention to the second of these.
Safari – errors opening local Home page, and others
Once Safari has started up and connected to a remote page, these problems usually vanish, so can be safely ignored. They also appear to occur most commonly when the Develop menu is enabled; turning that off may make them disappear, but you then lose the additional features of that menu. This bug was present in 12.0 and persists in 12.0.1.(Thanks to Manoli for pointing this out.)
iTunes – can’t play full-screen movies when 5K display in non-default resolution
If you’re using a 5K display, such as that of an iMac Pro, in a non-default resolution, trying to play a movie using iTunes 12.9 can result in a real mess. iTunes thinks it is showing it in full-screen, but in fact the movie is letterboxed into the centre of the display. Menu commands to switch out of full-screen mode are non-functional.
If you are struck by this, quit iTunes, switch your display back to its standard resolution, and open iTunes, which should then play the movie correctly. You can then quit iTunes, resume your non-standard dislay resolution, and when you next try to play a movie in iTunes it should work properly again.
Font Book – can’t disable or remove fonts in /Library/Fonts
Although Font Book used to be able to, and its Help book still claims that it can, since 10.14 (including 10.14.1) it has been unable to disable or remove any font stored in /Library/Fonts. It can currently only disable or remove those in ~/Library/Fonts.
The well-known workaround is to create the folder /Library/Fonts (disabled), or similar, and move fonts to that folder to disable them.
Appearance – grey/gray accent turns ‘traffic lights’ grey too
In the General pane, set the Accent colour to grey. Whether in Light or Dark mode, the ‘traffic lights’ at the top left of every window then show just three grey lights instead. Now which end was red?!
The only workaround is not to use the grey accent.
(Thanks to simweb for reporting this below.)
Finder – incorrect column width
Bugs known to have been fixed from 10.14
Two of the three vulnerabilities in privacy protection appear to have been fixed. These include that discovered by Jeff Johnson, that of Patrick Wardle (according to Apple’s security notes, where it is listed as a vulnerability in the Dock), but not that in
Safari ‘smeared’ image previews during download.
(Updated 19 November 2018 with iTunes bug.)
