macos – Big Sur: remove per-user permissions for builtin apps

I am trying to create a limited user account without access to several builtin apps, such as Terminal.

Changing these apps permissions either through Finder or chmod failed – I assume due to them being in the write-protected /System volume. I’ve also tried to copy them over to /Applications and change permissions on the copy instead, but that only leads to them appearing twice in Finder.

Is there an officially sanctioned way for access control left that doesn’t involve me disabling SIP and remounting /System as read-write? Screentime is not an option for me, because I’ve found it to be highly unreliable on iOS.

big sur – Unlock MacOs with fingertips doesn’t work on Big Sur

I’m trying to unlock my MacOS Big Sur with a fingertip. During the initialisation process, I configured my fingertip correctly but when I try to unlock my MacOS it doesn’t detect it.

If I go in “System Preferences” under the menu “Touch ID” this is what I see:

enter image description here

Then I decided to check the “Unlocking your Mac” option, I fill the password but if I open “Touch ID” for the second time “Unlocking your Mac” is still unchecked.

Why? What can I do?

MacBook Pro doesn’t automatically go into Hibernate/Safe Sleep on empty battery (M1/Big Sur)

Long gone are the times when my MacBook Pro 2012 automatically went into hibernate when the battery was low. I always blamed it on my old battery. I recently bought a MacBook Pro M1 though, and was pretty certain this problem was no longer an issue.

I was wrong. The problem still persists. I have a fresh install and double-checked that I am on default settings.

pmset -g:

System-wide power settings:
Currently in use:
 powernap             1
 sleep                1 (sleep prevented by powerd, coreaudiod)
 Sleep On Power Button 1
 ttyskeepawake        1
 tcpkeepalive         1
 disksleep            10
 standby              1
 displaysleep         2

Comparing it to my old MacBook I can see that a lot of settings are missing.

Although the setting hibernatemode doesn’t show within pmset -g, I can see that it still exists and that the default is still 3, because whenever I change it to a different value, the otherwise disabled button Restore Defaults in System Preferences gets enabled (Thus I obviously changed the defaults).

So: What the heck is going on?! Has this feature been removed?

macos – Big Sur screen sharing constantly locking desktop

I recently upgraded my two Macs to Big Sur and use the first mac (mac1) to connect to the other via screen sharing (mac2)

Since upgrading, mac2 (the one that is sharing its screen) continuously locks the desktop while I am connected via screen sharing. I can unlock it (password or touch id), but it will lock again. Sometimes it works for a few minutes, other times it will immediately lock over and over right after unlocking. It’s basically unusable at this point.

The laptop works fine when I am not sharing the screen and this problem never happened until I upgraded to Big Sur. Are there new policies or any configuration settings I need to be aware of regarding screen sharing?

I haven’t found any specific set of steps to reproduce the problem other than it always happens.

big sur – MacOS Big Sur – how do I disable/ skip verify on opening dmg

I have 2015 MBA running Catalina that at some stage in the past I managed to configure that when opening my own created dmg files (used for business data storage with encryption security) it no longer goes thru the verify process when opening – just straight to providing the password.

So I have bought a new MBA and installed Big Sur with clean install. Now I get the verify process each time I try to open my dmg files. Tried the “defaults write com.apple….. skip-verify” to no avail. (In fact on my 2015 MBA, this flag is not set anyway).
IT is extremely time consuming to have to go thru the verify process every time I want to open (several) of my data dmg files.

Does anyone know what I need to do to disable this verification step when opening my dmgs? (They are also kept on an encrypted NAS for security as well).
TIA.

terminal – Fail when installing package “pyplatefit” on macOS Big Sur

When I am installing software using python setup.py install I got an error as follows.

Error: Rank mismatch in argument 'c' at (1) (rank-1 and scalar)

Is there any way to fix it?

Is there an SVG version of the Finder icon from macOS Big Sur?

In a project I’m working on, we have icons to represent different platforms. Since we support both macOS and iOS, we don’t want to use the Apple logo for either because it’s ambiguous between those two platforms. Currently we are using this icon to represent macOS, since it’s the Finder icon from macOS Big Sur:

However, we are looking to replace the platform icons with SVG files (preferably lightweight ones), so that they will look great at any resolution, while being smaller in file size. Is there any way I could get an SVG version of this icon without re-creating it?

macos – Most Apple apps wont open on Mac Big Sur

So this issue has been happening for a while now, ever since I updated to Big Sur, apps like Safari and App store will not work. For Safari, I can open it and enter a url, but it will never actually go the link and follow through.

App store will open but just stay blank
Music I can see my previously downloaded music, but I can’t search for new music.

I tried doing a back up for a restart but the backup would end up freezing at 74 mb out of x GB.

And for the first few weeks, any time I decided to open a new app, it would take a couple minutes to open, now that issue is gone but the apple apps are still broken
