Today I looked into a problem with my father’s late 2012 Mac Mini running MacOS High Sierra. Since about a week the machine got terribly slow and often unresponsive. It turned out the system was extremely busy with

I really enjoy listening to music while working on my Macbook using a bluetooth headset or speakers. However, as I am switching quite often between BT devices, sometimes the audio playing no longer works and I had to restart to get sound over bluetooth again. Today I found out how get it working again without restarting.

I am running VMWare’s free vSphere Hypervisor (formerly known as ESXi) on my Mid-2011 Mac Mini Server (Macmini5,3) for many years . Earlier this year VMWare introduced vSphere Hypervisor 6.7 but as it was not really clear what it would add and I had a stable environment I decided not to upgrade (yet) when it came out.
However, ever since Apple introduced the APFS filesystem with MacOS High Sierra, special care was required to install (or upgrade) a MacOS VM on vSphere Hypervisor as the built-in EFI boot did not support this. Since I had to create a new MacOS Server today, I decided to give this update a try to see if it would support MacOS High Sierra. Documentation was not very clear on this, but it turned out that with this version of vSphere Hypervisor, MacOS 12.13 (as well as 12.14!) is supported, as this is how the dropdown when creating a new VM now looks like for MacOS:
This post contains the steps to perform an upgrade from vSphere Hypervisor 6.5u1 to 6.7 on my Mid-2011 Mac Mini Server, including the installation of the (not included) VMWare Tools image for MacOS.

As part of the migration of my MacOS Server to Linux the next service to migrate is my PostgreSQL engine. Although PostgreSQL had already been hidden in MacOS Server for some time, it still was included (as internal services like ProfileManager and Calendar and Addressbook Server depend on it. Despite it being hidden, I had still enabled it (manually) and hosted my PostgreSQL databases on my MacOS Server for ages. Despite migrations sometimes being a pain (i.e. not automatic) this worked well so far, including integrating it with the MacOS Server way of using transaction logs for offline backups. (so I will also have to look for a new way to do this). Continue reading “MacOS Server Replacement #2 – Migrating PostgreSQL”
As part of the migration of my MacOS Server to Linux the first service to migrate is my MySQL 5.7 engine. Although MySQL is not part of MacOS Server anymore for a long time (and I had installed it separately), I will cover the migration here as 1) I still had it running on my MacOS Server and 2) the migration wasn’t smooth so decided to share my learnings here.

Today I noticed that there was a new update for MacOS Server that had quite a lengthy explaination:
As per Apple Knowledge Base article HT208312, the once great Apple Server product as this fall will be reduced to:
- Profile Manager
- Open Directory
The rationale of this is, according to Apple:
In fall 2018, Apple will stop bundling open source services such as Calendar Server, Contacts Server, the Mail Server, DNS, DHCP, VPN Server, and Websites with macOS Server. Customers can get these same services directly from open-source providers. This way, macOS Server customers can install the most secure and up-to-date services as soon as they’re available.

For quite some time I am an happy user of Open Whisper Systems’ Signal Messenger phone application as alternative to WhatsApp. The fact that this solution is open source and that the exchange of messages (and now also calls) is secure and that this can be verified by anyone are important and valuable. I use it on my phone but as I spend most of my time behind a laptop and still (call me old-fashioned) prefer a real keyboard over a touch screen I have been looking for a way to use it from my laptop as well.

After installing of OS X (MacOS) Sierra update 10.12.2 I noticed that SSH connections started to ask for the password of my RSA key. This wasn’t how it worked before and not what I want (as I trust my MacBook Pro) as it is quite annoying.
For the current session the solution was quite simple, just run the command:
There seem to be many discussions online in what is causing this (i.e. here) with strange theories and odd (or not working) solutions. As documented also here, the root cause seems to be that the upstream OpenSSH code has changed and that Apple’s developers are following the changes.
The solution is fortunately quite simple: just create a file called
~/Library/LaunchAgents/org.openssh.plist with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<string>Add SSH Keys to SSH Agent</string>
And from the next login onwards your SSH key will be added to ssh-agent again.
After yesterday’s upgrade of my Late 2006 Mac Mini (MacMini1.1) it was time today to see if I could get OS X 10.7 (Lion) working on it. As per discussions on Apple’s discussion forms this should be possible (as the hardware supports after the upgrade I did). However, the standard OS X Lion installation did not want to install on this hardware yet. As per the discussion on MacRumors.com I had to remove the file
before the installation wanted to start. Once I did that, I could do a clean install on the new SSD Harddisk withougt any issues or additional hacks needed. Also transferring the users, apps and settings from the old system still on the external USB harddisk went fine and actually totally surprised me (I never used it before) as it turned the clean install in a totall usable system including the configuration of the OpenDirectory server.
After the installation it is important to enable Trim support on OS X to extend the lifetime of my SSD harddisk with the excellent tool Chameleon.
Right now I am very happy with the end result: a Late 2006 Mac Mini running OS X Lion (10.7):
Obviously only 3 Gb of memory is available as that is the max. the hardware supports, but still this is a very good solution to have a 2nd Mac Mini system for my children.
One of the Macs in our house is a late 2006 model Mac Mini (MacMini1.1 model MA206LL/A). The machine itself still works hapily with Mac OS X Leopard (10.6), but it only has 2Gb of memory and since its harddisk broke a while ago, it is working from an USB harddisk. All in all technically still OK, but terrible user experience as it is just slow.
Today I did some investigation on the Internet to see to what extend this old machine can still be upgraded and bumped into an interesting overview on xlr8yourmac.com. It turns out that the basics are quite good and with a few changes it can still be used for some time:
- CPU – currently a Core Duo that could be replaced with a Core 2 Duo
The Core Duo processor is a 32-bit one that does not support 64-bit OS X. Fortunately the processor is on a socket (and not soldered to the main board) and its pin layout is identical to Core 2 Duo models. This is also being discussed on Apple’s discussion forum (still exists so Apple is not stopping it) and according to posts on MacRumors.com others have done this successfully, so this is definitely something I will try. Guess what, there is even a step-by-step guide on iFixIT on how to do it!
- Memory – currently limited to 2GB but potentially could support 3Gb (of 2x 2Gb)
Memory is limited to 2Gb (2x 1Gb) with the Core Duo processor, but the Core 2 Duo can support up to 4Gb (2x 2Gb) of memory. Unfortunately the MacMini1.1 model firmware does not support it but it turns out to be possible to flash the firmware of a MacMini2.1 as the folks on the NetKas forum explain. The links to the firmware no longer worked, but I found them on a French Mac Forum thanks to this post. After this upgrade 3Gb can be used, which is still 50% more than the machine had.
There is a separate step-by-step guide on iFixIT for replacing the memory, but I don’t think I will need it as I will do it when I replace the CPU.
- Harddisk – currently broken 5400rpm 80Gb disk, replacing this with a 60Gb SSD harddisk is a no-brainer
Replacing a broken harddisk for an SSD disk is nothing fancy, though it is important to enable Trim support on OS X after replacing it when you use a non-Apple disk. For this I found the excellent tool Chameleon some time ago for my Macbook Pro.
Also for this step there is a step-by-step guide on iFixIT, that I won’t need either as I will install the new harddisk when I replace the CPU.
- Software – currently OS X Leopard (10.6) is the maximum
Replacing the Core Duo CPU for a Core 2 Duo would turn the MacMini1.1 effectively into a Macmini2.1, which is capable of running OS X Lion (10.7) according to discussions on Apple’s discussion forms. There is apparently only one hack needed (removal of a file on the installation media) to be able to perform a clean install according to a discussion on MacRumors.com.
As I am not that uncomfortable with opening my old Mac Mini (did it before when I added memory) and the other steps appear doable, I will give this a shot. I just ordered the components and plan to perform the upgrade next weekend (assuming all parts will be in).
