Upgrading Mac Server 10.8.5 to 10.13.1

I recently had to upgrade a couple of servers running 10.8.5 to High Sierra. And found that it had to be done in stages- you can only go up 2 version of operating system at a time- try 3 and you’re SOL. but 10.8 to 10.13 is 5 versions of upgrade? So how did we do it?   Backup, Upgrade to Yosemite 10.10.5, then log in to App Store. Click ‘install’ for Server. It will ask if you want to download an older compatible version, say yes. Install, test. Backup Upgrade to Sierra 10.12.6. Install Server.app v5 and test.┬áBackup...

Installing ESXi on a Mac- The Basics

I’ve written a number of other articles about ESXi, but I’m trying to deploy a 2013 Mac Pro into my lab and realised I was back to square one because I hadn’t documented the first, baby steps. So here we go- Download the latest .ISO from VMWare. You need to register to be able to do this Get 2x 8GB USB sticks, and format both to FAT32 using SDFormatter. One is for the installer .ISO and the other is your installation target- it will boot your host, leaving the internal drive available for VM storage. Use different brands if...

Making a Digital Info Sign

My son has a habit of asking what’s on about 15 times day, and if that weren’t bad enough, he often comes into my office and uses my work computer to look at the calendar. Something had to be done. I’ve seen a lot of digital signage projects (and ‘magic mirror’ projects) on Reddit so I started planning. A Raspberry Pi would easily display the data, and I wondered if I could get a display with a built in USB port to make the wiring neat. It turns out you can, as long as you’re prepared to settle for a...

This is one of the most popular posts we have, especially now that low capacity SSDs are everywhere. It’s been updated from the 2013 version to reflect the current state of play with tips for Sierra etc. Enjoy!   This article came about because of a client who is overseas. He wrote me an email saying that he couldn’t figure out where all of the space on his MacBook Air SSD had gone. This question doesn’t have a simple answer, so I’m writing this to help him, and everyone else out. Here’s the problem- There...

More Storage for Tiny Disks

Let’s face it, Apple has been pretty stingy with the size of the SSD drives that they put in their machines. Although that is changing now, a lot of people are quite happy with their MacBook Air or MacBook Pro- apart from the fact that the drive is always full. This is particularly painful if you’ve bought an 11″ machine with a 64gb drive or a 13″ with a 128gb drive. Also remember that wear levelling gets harder and harder as your drive gets more full, meaning that your drive may prematurely die…. To buy a larger...

My Email is Down!

This is one of the most common support issues we face, so it’s worthwhile exploring a few solutions. Usually, the server is working fine and the issue can be traced to one of a number of other gremlins. So, how do we figure out exactly what has gone wrong? Warning- if you use the wrong username and password combo too many times, or other reasons– the server may ban you. So even if you get the credentials correct, you still won’t be able to log on! Don’t just guess passwords- look them up using Keychain Access Step 1....
