Mail on Mac OS Server v10.13.4

I’ve been trying to get a new client on board and as part of that I’ve made a list of things that need to get fixed for that business to operate reliably. One of the dangerous things they are doing is running Mail Server on a Mac. This is about to become an unsupported config, so there is some urgency in getting a replacement service running. And of course the server was compromised, blacklisted and I’ve just spent nearly 3 days running around with my hair on fire. With most mail servers it’s a simple task to check the...

Managing Mail Storage- cPanel

One common issue for clients is the limited amount of storage available with cPanel based hosting. However it isn’t really a problem if you learn how to manage it properly. This means you need to take action when you get one of those ‘Mailbox quota notification’ emails.   Retrieve Your Email Password (skip this step if you know your email password) You NEED to know your email address and password. Can’t remember your password? Go to Applications/ Utilities/ Keychain Access   Open Keychain Access Go to the search box at...

Increasing Disk Space to a Mac VM in ESXi 6.5

I typically allocate my Mac VM’s 40GB of drive space which is fine for most normal operations. Unfortunately I recently came across a situation where I needed more space for an existing VM. I knew that ESXi could do this, and I knew that Mac OS can do this, but could they do it together? Well…no. Sort of. But not really. Here’s the problem- you can shut down the VM, use VMWare Fusion (v10.11) to increase the virtual disk size, then boot the VM and Disk Utility will see the extra space. You then delete the free space and Disk...

Pi-Hole on Synology in Docker

This is just a short note on installing this. It is a very quick process, but it took me way longer than it should have because I misunderstood a couple of things.   Why? Pi-Hole is a very lightweight DNS server that you can place on your network. It will ignore calls to most advertising sites, effectively getting rid of advertisements. It’s great because it does not require anything installed on individual devices, works for your entire network and is simple to set up. Here’s a link to the Pi-Hole site I have plenty of spare...

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. Backup Upgrade...

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...
