You should try Stellar Data Recovery app. I lost data on my internal SSD and this helped me get it back. It sounds from the comments that your data may have been overwritten already, but this app is a free* download and may help you confirm this.
* Download the free trial version to scan & preview all the lost files and folder. Currently the ...
I saved my SSD partitions with TestDisk
My partition table did gone and My SSD has two partitions, first one is NTFS and second one is mac os extended.
And I save my partition table like this guide.
If you are able to repair you drive, then you will need to be running at least Sierra in order to mount the macOS partition on the SSD via USB.
Below are two possible solutions.
Using a Third Party Tool
Since you already have the SSD connected as disk2 in a USB port, a simple solution would be to download and use gdisk.
The current gdisk installer is ...
This is the official answer from me on what fixed the issue.
If you run into this same situation(rare case really) this is how it was fixed.
The background: MBP 2016 with TB, updated normally, converted to APFS and had at one point windows running on it with bootcamp.
I decided to format the drive and reinstall clean because i had a lot of clutter on it and ...
Helo, and welcome to Ask Different. (Please excuse my spelling, for some reason Ask Different deletes the word if I start with the word hello.)
Your problem might be that you're restarting into your Recovery Partition instead of your external Installer.
You can boot into your installer by pressing Option when restarting, and then selecting to restart into ...
The command you are using adds any significant amount of free space immediately after the APFS container partition. By adding the values posted in your Update 2, you can see the APFS partition container is already at the end of the drive. There is no significant amount of free space to add.

The WDC WD100... and the Mercury Electra are devices. They represent the physical drives that are attached to your Mac.
Devices contain one or more volumes. Macintosh HD is a volume on the WDC device. There will be other volumes on that device that aren't displayed.
The Mercury device uses Apple's new APFS format. This uses a structure called a Container ...
As an educated guess after reading around, the likely reason that the High Sierra container could not be resized was that it was not contiguous with the free space.
I have now zeroed-out Mojave and cloned the contents of High Sierra to there, whereupon I can resize that partition to occupy the free space.
For me it looks like you need to resize the container first. So something like
$ diskutil apfs resizeContainer /dev/disk0s3 500g
should help to avoid the error message you get on your second try.
I've got not much knowledge about the diskutil, but as far as I know Apple software overall, this seems to be the step you are missing here.
You model identifier is either MacBookPro9,1 (15" screen) or MacBookPro9,2 (13" screen). The drive does work in your Mac as a replacement drive for the original internal drive. In other words, the drive can be found on the Kingston website for System Specific Memory for Apple MacBook Pro 15-inch (Mid 2012) and System Specific Memory for Apple MacBook Pro 13-...
I am not familiar with that particular SSD, however if it is a standard form factor 2.5" SATA drive then it should work. This take apart on fixit.com shows replacing the HD in a 13" 2012 MacBook Pro.
I don't know where you heard that Macs can't boot from an optical drive but that is patently false. macOS used to come on optical media that you had to boot ...
Apple says: RAM is not user-installable on Mac mini (2018)
While I do not know what this means in terms of voiding the warranty…
Apple does not consider the RAM in a Mac mini (2018) to be user-installable.
The Apple Support page Upgrade or install memory in your Mac mini says:
Mac mini (2018) does not have user-installable RAM. You can ...
Added as an answer after comments...
Initially a guess, that the disk was formatted APFS, which would be unreadable by El Capitan.
Upgrading to High Sierra would enable the disk to be read & written as normal.
As regards permissions; you could either add yourself to the user list, as an ACL, or you could just Get Info on the drive itself & check ...
Moving the entire user domain, instead of just the folders for Videos and Photos may be overkill, though it would keep things simple. You're not going to see any advantage from moving preferences, audio files, Word docs, etc, as they are too small and not causing any bottleneck.
There's no disadvantage either, except that if the Mac boots up and can't find ...
I got a 2018 Mac Mini as a gift but only a 256GB drive. My user profile is almost that size. So I got a 1TB SSD and a nice USB-C/Thunderbolt case and copied the profile over there. Works a treat for me.
Once you have copied her profile to the external drive go into System Preferences > Users and Groups and Control Click on her user name and select ...
Holding down the option key will involve the Startup Manager. If you hold down the control key before making your selection, then your selection will become the default. This works for both internally and externally installed operating systems.
If Windows on the external drive is the default and the external drive is not connected, then the firmware will ...
The easiest method to install Windows is to use the Boot Camp Assistant. However this method limits where Windows can be installed. This limitation can be overcome my avoiding the use of the Boot Camp Assistant, but is increases the complexity of the installation process.
The Windows installer GUI (Graphical User Interface) can also limit where Windows can ...
