Cannot seem to install VMware vCSA 6.7 cert on macOS 10.13.6 High Sierra

Trying to install the web certificate for my vCenter Server Appliance (vCSA 6.7) on my Mac Mini (running macOS High Sierra 10.13.6). I download the cert.0 file, change the extension to .crt and double-click the file, Keychain Access opens…but then nothing. The cert does not get installed. This is exactly how I’ve always installed the cert on machines before. Where could be going wrong here?

Cannot SSH into Cisco switch or pfSense route from Mac Mini (macOS High Sierra 10.13.6)

Errors message in Terminal are (switch 1st, router 2nd):

How do I clone from a Mac OS Extended (Journaled) spinning hard drive to a new SSD on 10.13.6

I have a MacBook Pro (13-inch, Mid 2010) with a 500GB spinning hard disk boot drive with High Sierra 10.13.6. Disk Utility reports the drive as “SATA Internal Physical Volume – Mac OS Extended (Journaled)”. I ran First Aid on it and it came back good.

I have a 500GB SSD in a USB enclosure.

I booted into Recovery and started Disk Utility. I erased the SSD and chose plain APFS format (the four options available are all APFS variations). I tried restoring to the SSD, but the Restore window shows “None Available” in the “Restore from:” drop-down.

I read something that suggested converting the boot disk to APFS, but that menu item is grayed out when I select that drive.

How can I get the contents of this spinning hard drive onto the SSD?

How do I get the 10.13.6 update to (reboot and) install?

I have macOS 10.13.4 on my Mac. In the App Store, it shows 10.13.6 as an available Software Update.

When I click the “Update” button, I get the notification in the top-right corner of my screen:

Restarting Your Computer                                              [Restart] Your computer will restart in 43 seconds     [ Later ] to install updates. 

When I click “Restart” (or wait for a minute), the App Store window shows a sheet that says:

Available updates have changed. Click "Show Details" to see the available updates.                             ( Cancel ) ( Show Details ) 

This aborts the restart. If I click “Cancel”, the sheet goes away, and the reboot doesn’t happen. If I click “Show Details”, the sheet goes away, and the reboot doesn’t happen.

If I quit the App Store first and then click “Restart”, it opens the App Store again and shows me this sheet.

If I quit the App Store and choose plain “Restart” from the Apple menu, it restarts my Mac, but doesn’t install the update.

How do you install the 10.13.6 update on 10.13.4? What am I missing?

Unable to partition mid 2014 MacBook Pro SSD on Sierra 10.13.6

Just trying to partition my 500GB SSD so I can dual-boot linux and my MBP doesn’t want to let me do it. I’ve watched countless videos and no one seems to be having my problem. I attempt to the partition in Disk Util,enter image description here first select my Apple SSD and hit partition. When I hit the “+” to add a partition it doesn’t auto divide my SSD in half, it only lets me create a 1.6GB partition. I have over 240 free GB’s of storage. It won’t allow me to enter it manually, and nothing I have tried has resolved this regardless of format etc. and for some reason no one has shared how to partition from the command line that I have found. There’s articles showing how to do everything except for partition in the command line and I’m too timid to attempt it without being confident about it working.

App Store won’t let me update from 10.13.4 to 10.13.6 – why?

I’ve got 10.13.4 running on a MacBook Pro.

When I go to the App Store it says in order to download the latest version of iMovie I need 10.13.6.

But there is no option to download 10.13.6 via the App Store.

Any ideas why this would be and apart from downloading the combo update file direct from Apple’s website (eg not through the App Store) how could I get it to work ?

iPhone7 (ios 11.1.2) failed to connect to Macbook pro (MacOS 10.13.6) with error msg “Installation Failed”

Basically, I am having the error which is the same as https://discussions.apple.com/thread/8464414.

Anyone have any ideas how to fix it? Thanks a lot.
