At the moment, I’m in the fortunate position of having not one but two 2008 MacBook Pros, both A1260 2.4GHz models, both with SSDs and one with a matte display and the other glossy. It’s a long story how I went looking for one and ended up with two but for another time.

Anyway, at the time I installed 10.15 on both via the amazing patcher by @dosdude1. There are/were a few glitches but overall, a success.

Recently, I’ve been thinking of passing one of these machines on but before I do, I thought it would be interesting to compare a Mojave installation with the Catalina, given that the hardware is identical. So that’s what I did.

First observation was that the Mojave installation was easier and more or less just worked. I chose the older format for the partition as opposed to APFS as I wanted a cleaner boot experience.

Second observation was that the boot-to-login time was definitely quicker. Just to be sure I had a drag race and the Mojave installation got to login screen in 51 secs while Catalina took 1 min, 12 secs.

Third observation was that the Mojave MBP seemed quicker when surfing the net. Using Speedtest.net I checked and was surprised to see the Mojave MBP achieving the full 73 Mbps download speed while the Catalina MBP only managed 22 Mbps. I checked several times just to be sure.

Both installations have trouble with keyboard backlighting. While the Catalina MBP has to have a little app installed to manually switch the backlight on and off, the Mojave MBP backlight is permanently on but can be controlled with the level function on the keyboard.

On balance, while it’s great to have the Catalina option if we want the very latest this hardware can support, I think I’m going to stick with Mojave. It just feels nicer and from my basic testing, works better on the A1260. If it wasn’t for the keyboard backlight, it’d be perfect.

Just to check that it’s not a hardware fault on the Catalina MBP which is slowing its networking performance down, I’m going to install Mojave on it too at the weekend and see if it makes a difference.

Anyone else with similar experiences?

Even on supported hardware like my 2015 Pro, Catalina was a slow buggy mess of a release. Compared to both Mojave and Big Sur, it is slower during general day-to-day use. It took till somewhere around 10.15.5 to fix random kernel panics!

Ended up going back to Mojave until Bug Sur (the first few dot releases of Big Sur) came out, then went back to Mojave until 11.6.2, then came back up to Big Sur and have been happy since! Currently (see my sig) running 11.7.1 with no issues.
 
Well, I removed Catalina and installed Mojave on the other A1260 and just as expected, network problems were solved and the boot time has dropped. I’m leaving it at that as Mojave seems to be the most stable, best performing version of OSX on 14 year old hardware.
 
On that note, on the 2008 aluminum MacBook (not MBP), High Sierra works just likely natively, which makes sense since it's basically the same hardware as the late 2009 MacBook, which officially is supported by High Sierra.

2009 White Unibody MacBook

GeForce 9400M
10.13 High Sierra

It was especially a big kick in the teeth for us 2009 MacBook Pro owners, as it is also basically the same hardware as the 2009 White Unibody MacBook, and was released the same year.

Here's the loading times from the boot menu to the log-in screen on my 2010 11" MacBook Air 2GB C2D:
  • Mojave 37 seconds
  • Catalina 40 seconds
I think we can regard the three-second difference as negligible. :)

As I've already discussed elsewhere, everything works perfectly out of the box with both operating systems thanks to the masterwork of DosDude and the level of performance on such a modestly specced machine is all the more impressive.
