How do I get the ‘Find My’ map back in the Messages app ‘details’ popup on macOS?

I used to have a ‘Find my’ map on the details popup in Messages, useful for quick access to that info.

It disappeared around the time I upgraded to Catalina, so I assumed the feature was pulled. However, when I got a new MBP 2 weeks ago, the feature reappeared, so there as probably something wrong with my old installation. It has now disappeared again, so why is that and how do I get it back?

macos – How can I select “Allow” from System Preferences -> Security Panel to allow the installer to run from TERMINAL

I am connecting to a MAC OS X computer remotely from my Windows machine. And I am trying to install Docker on the OS X machine. In order to do this, I am running “brew cask install virtualbox” command. However I get an error. From some websites, I learned that I should enable the “Allow” option from System Preferences -> Security and Privacy.

But I can’t do this because I only have access to the terminal (because I am connecting from another machine). I don’t know how to enable this option from the terminal.

Thank you

macos – Booting iMac from External SSD & UASP support in iMac, Docking station or USB to Sata Adapter?

I have Late 2013 iMac which has 5400 RPM HDD and I find it really slow. So, I purchased a Crucial MX500 SSD. I have now cloned my HDD to SSD using superduper and then booted from it. It worked. But I have run into the following issues:-

  1. After some time of inactivity when I return to unlock my iMac and use it. It doesn’t work. I need to force shutdown and restart again. Why is this happening? Does power supply to external SSD (connected in USB) get cut off? Do I need a docking station that provides power supply as well or USB 3.0 port provides sufficient continued power to External Bootable SSD?
  2. The speeds which I’m getting for both read & write are only about 100MB/s, which is below my expectations. I couldn’t find any thunderbolt to SATA III adapter in India. Should I consider using UASP supported SSD enclosure? Does my iMac late 2013 support UASP?


macos – Is there any advantage to different file systems on microSD?

Yes, different file system have different advantages.

For example if you compare your current ExFAT with the macOS standard file format APFS or the older HFS+, you could gain several advantages by switching:

In terms of safety against “lost files” (where the drive is actually still good) both APFS and HFS+ have the advantage of being journaled file systems. This means that they track changes to metadata (i.e. not the file contents) in a form of log on the drive.

This means that if a data transfer is not completed due to for example power loss, yanking out the drive or software error, then the file system can “roll back” the change using the information from the log. Essentially this means that although the file transfer didn’t succeed, you wouldn’t end up with a corrupted drive and lost access to your files.

If the card is physically damaged or “broken” then no software file system can fix that of course – that’s worth keeping in mind. Always keep backups (this is true of any storage medium).

Note that there’s a big difference in the quality of SD-card. Don’t buy the cheapest ones – they’re usually not that reliable. However you can actually get very reliable SD-cards – they’re just in a different price range. I’ve been using industrial SD-cards for many years in a commercial setting where they’re exposed to high and low temperatures, vibrations, high endurance (i.e. SLC instead of MLC), etc. and you really need high quality SD-cards in those cases. I’ve had good experience with cards from Cactus.

In terms of safety in a broader perspective, the APFS file system supports full disk encryption. This means that you could have the data on your SD-card encrypted while using it as any other SD-card. If the SD-card is lost at some points, others would not be able to your read your data without your passphrase.

One of the disadvantages of APFS/HFS+ is that they’re not natively supported by for example Windows. If you try to use the SD-card with Windows, the files won’t show up without installing extra drivers and support software.

Regarding speed there is a difference between the file systems. A file system such as APFS or HFS+ is usually slightly slower than FAT32 for example as they have to do extra work in terms of saving logs, checksums, etc. However in practical use, the average user wouldn’t be able to tell them apart in terms of speed on an SD-card.

macOS Catalina screen recording permission to third-party apps not working

I need to use several third-party apps which require screen recording. However those apps do not appear in the screen recording list in security and privacy in macOS Catalina.

file conversion – Is there anyway to have macOS Photos bulk convert all of my past JPEG images to HEIC format?

I’ve seen lots of tutorials online explaining how to convert iOS HEIC files to JPEGs but I can’t seem to find any easy way to bulk convert existing JPEG photos to HEIC?

The reason being is I really like HEIC as a storage format: It easily makes image file sizes 5x to 10x smaller than JPEG equivalents which not only saves space but makes syncing the library to other devices quicker as well.

So I would like to convert all past images in my macOS Photo library to HEIC two take advantage of these benefits. Do any such tools exist? I would like to avoid a bulk export, conversion via non-Photos tools and then reimport because that seems messy.

Unable to Download macOS Mojave from App Store, error prompted: “Update not found, the requested version of MacOS is not available”

I’m running Catalina on a MB Pro 2019 and I’m trying to create a separate volume running Mojave through a bootable external device. I’ve been doing this earlier this year and I had no problem whatsoever doing it, but as of today, when I try to download Mojave from the App Store, as soon as I press the “Get” button, Software Updates prompts and I get this error: “Update not found, the requested version of MacOS is not available”, and I can’t download it. I’ve been using the App Store link found at step four of this link:

The result is I’m unable to download this version of MacOS and therefore I cannot proceed in the creation of a bootable device. Any advices on how to solve this problem? Does Apple also provides a direct link to download this OS?

ios – iPhone is unable to import photo on SD card that are copied from macOS

I have copied a bunch of photo files (jpg) from a macOS to a SD card.

enter image description here

Here is the details of the SD card as seen in Disk Utility

enter image description here

However when I insert this card to a SD card reader connected to an iOS device, the Photo app shows ‘No Photos to import’.

enter image description here

If the SD card is directly taken out from a mirrorless camera, I can use the SD card to import the photos in it with no issue.

So why this happens, and how can I fix this? I want to be able to import some photo via my iOS device.

macos – What is the purpose of the BSD pty/tty device files in /dev?

Backwards compatibility is the reason that these files are on the newest version of macOS. It is there to ensure that programs that expect this way of handling pseudo terminals still work.

You can open the /dev/ptyX# files the same way you would open /dev/ttys### files. You seem to have reversed the slashes in your command – please ensure that you are using forward slashes like this:

screen /dev/ttyw0

Note that this in itself doesn’t cause anything to happen. You have only connected to one end of the terminal pair. You would need to connect to other end as well to transfer some data.

As an example you could open one Terminal window and run the command above, and then open another Terminal window and run the command below:

screen /dev/ptyw0

Now if you type something in one window, it appears in the other (and vice versa).

The main factor in adopting the ptmx system was that the old system is very complex for programmers to use correct. It looks deceptively simple, but when you get into it, you’ll find that it is actually not.

One of the main problems is in determining which of the /dev/ttyXX files to actually use. I.e. you want to use one that is not in use by others. If you’re not very careful, two programs that want to open a new pseudo terminal at the same time could both mistakenly think that the same terminal is not in use by others, and then both start using it – causing all sorts of problems. The ptmx system solves this problem.

Edit question

MacOs, How with a laptop, use the mouse or the keyboard (connected in USB) To WakeUp?

On a laptop the WakeUp with MacOs is always achieved by pressing the PowerButton key, the USB ports are made inactive during standby.

DSDT or SSDT does not seem to be the solution. Maybe with the Kernel and a Kext dedicated to the mouse and the keyboard in USB?

Thank you for your answers.
