mojave – Change the rate of Desktop Photo image rotations to custom value?

I have a bunch of Mission Control desktops set up. I only work on one, but use the others to display folders of travel photos as desktop backgrounds, so when I have a break I can quickly go and revisit past trips for a while, then flick back to work again. It works pretty well – but (there’s always a but) the timing of the change of desktop background photo as they scroll through is just not quite right for me. The options are: change every 5 seconds, 1 minute, 5 minutes and so forth up to each day. The problem is 5 seconds is too fast, but the next increment of 1 minute is too slow. I want 30 seconds. I’m sure this is a tiny change in a tiny file somewhere. But where? Any ideas? (Mojave 10.14.6)

Mojave kernel panic related to Slack?

Macbook Pro 15″ mid-2015, MacOs Mojave 10.14.6 (18G7016), 2 external displays (HDMI and Thunderbolt-to-HDMI adaptor)

On 2 consecutive days I’ve had kernel panics that have restarted my mac. IIRC, the apps that were open both times were:

  • Slack
  • Webstorm
  • Chrome
  • Outlook
  • iTerm2
  • Apple mail

The 2 logs in my Diagnostic Reports folder both have the text:

possible cause: unlocking an unlocked mutex or


BSD process name corresponding to current thread: Slack

I also ran an EtreCheck report but it didn’t mention Slack in it’s possible causes (report summary attached). Any help in interpreting appreciated!

mojave – Chrome only refreshing display contents on scroll

I’m running Chrome version 91.0.4472.114, and Mojave 10.14.6. When I type in text fields in Chrome, not always but often, I will see no change on the screen until I flick the mouse to scroll the page, then it suddenly updates. For example, I just typed this sentence without seeing it until the end, when I scrolled. What could possibly be the issue? I’m not finding anything in searches. Firefox and Safari are fine.

terminal – Unable to reinstall MacOS Mojave on a hardware modified, mid-2012 MacBook Pro

I decided to reinstall Mojave onto a mid-2012 MacBook Pro that I purchased second hand in June 2020 & modified some of the internals of*. I have a lot of files from previous backups of files as well as from the last time I used Windows in 2018, & it was beginning to get a bit glitchy. While I did follow the instructions on the Apple website to make a bootable USB stick with Mojave on it with Terminal, I don’t think that I formatted the USB correctly.

It also gives me an error that says “This copy of the Install macOS Mojave application is damaged and can’t be used install MacOS.”

The previous owner had installed Catalina onto it, but I’m also an artist who needs 32-bit app support. Last year, I managed to get a USB stick with Mojave on it working (I currently don’t have access to it), but I’m beginning to think that’s why I can’t reinstall Mojave.

Terminal tells me it’s on Bash version 3.2. I’ve tried internet recovery (which has never worked with this machine), & changing the date to some time not long after Mojave’s original release date.

I’m at a complete loss.

*I replaced the original, failing 750GB HDD with a 2TB SSD; replaced broken super-drive with a SATA adaptor & a 1TB SSD; increased RAM to 16GB; replaced depleted battery with fresh one. I didn’t buy them all at once. – Notes in Mojave launches FaceTime – Notes in Mojave launches FaceTime – Ask Different

bootcamp – How to install Windows ISO on a single partition of external HD on Mojave?

What it says on the tin.
BalenaEtcher straight up doesn’t offer the option to select individual partitions and UnetBootin… well, straight up will not open. I click, it’ll ask if I’m sure I want to open it, and then the icon will pop in and right out of the dock.

Also, what I’m doing this for is to attempt installing Windows 7 on a partition of the boot drive and then upgrade it to 10 from inside the install itself so I can 1. Work with a sub-4GB ISO file which apparently makes software happier and 2. Upgrade from pirated to legit Windows. There very possibly may be flaws with this plan (especially since the Boot Camp drivers in another partition of the drive in question are made for Windows 10) so if there are feel free to let me know.

How to install Mojave on a 2018 Mac mini that came with Big Sur?

I recently bought an open-box 2018 Mac Mini to replace a much older one before it dies. I wanted something that would run Mojave since I have some important, orphaned 32-bit software I need to run. Unfortunately (or not) the mini came with Big Sur installed and Recovery won’t go back to anything earlier. My plan now was to install Mojave on a separate partition so Big Sur would still be around to fiddle with. I have been unable to do that.

I used softwareupdate —fetch-full-installer etc. to get a recent, clean copy of the Mojave installer. I then used —createinstallmedia (with and without —download assets) to make a bootable installer on a thumb drive. It actually took me several attempts before it didn’t give an error message (one or more of the BridgeOS packages couldn’t be downloaded.) The resulting installer-on-a-stick boots, the apple logo comes up, and a progress bar starts. Eventually (maybe as long as a half hour) the bar gets to the end and it just sits there. No error messages, no nothing. Note: I did NOT wipe the mac mini’s internal drive before trying to boot the installer. I’m willing to do that if necessary, but only if someone tells me they’ve successfully installed Mojave that way and couldn’t do so without doing the erase.

I took the fetched installer over to my 2012 MacBook Pro and it executed fine and I was able to install Mojave on a partition on an external drive and boot from it (on the MacBook Pro.) I also took the thumb drive bootable installer over to the MacBook and it booted fine; I quit before actually trying to install Mojave, but that at least showed that the installer on the thumb drive appeared to work. So, the installer’s good and the thumb drive is good.

I then tried making a Catalina installer the same way. That worked like a charm and I was able to install it on a separate partition on the mac mini so now I could dual boot into either Big Sur or Catalina.

Whether relevant or not, I tried disabling SIP and Gatekeeper (spctl) on the mini, but that didn’t help. Suggestions? It certainly should be doable since I understand that model Mac mini originally shipped with Mojave. I’m willing to completely wipe the Mac mini’s drive if that’s necessary, and guaranteed not to brick it, but I shouldn’t have to do that, you’d think. There are some possibly relevant threads here that I’ve skimmed, but I didn’t see any that described exactly this problem. I’m pretty Mac savvy, but when it comes to firmware updates and the T2 chip I’m afraid I get lost.

So, let’s restate the question. How do you install Mojave on a 2018 Mac Mini that came with Big Sur? (Either on a separate partition or replacing Big Sur.) You get extra credit if you can tell me why the installer hangs for me at the end of its boot. Has anyone else encountered this problem? I know you can “solve” it by using any of several Virtual Machine packages, such as Parallels, but that would be my last resort.

finder – Automator “New File” workflow in Mojave returning “Not authorised to send Apple events to System Events.”

I have copied a workflow to create a new file from within the finder, saved in ~/Library/Services/. It runs fine from Automator and appears in the Finder > Services menu, but there’s no “services” menu when clicking in a blank area within a folder.

I’d expect to right-click on a blank space in a folder (or the desktop) and use the contextual menu and activate it.

The main issue is that the script runs fine from within Automator, but not from the Finder:

The action “Run AppleScript” encountered an error: “Not authorised to send Apple events to System Events.”

Has anyone else had this issues with a working script?

macos – notes sync mojave vs ios14

I remember that I read somewhere that notes in iOS 14 will not be compatible with notes in Mojave. But I cannot find any more updated information. Some claim that they only stop working after one upgrades the format in which they are saved on iCloud.

Can someone please post their experience/knowledge whether it is safe to upgrade to iOS 14 without losing sync of notes with OSx running Mojave.

Finally, can you please list what will break down by such an upgrade (iPhone to iOS 14 and osx left at Mojave).
