Archicad 19 INSANELY SLOW to launch

Not applicable
I just updated software from Apple, and what had been tediously slow has slowed even further. ( More than 10 minutes to launch program and open file.

This is after a cold boot.

Is my Mac too slow? Is the operating system causing a log jamb?

Here's my specs, in case my profile is out of date....

Processor Speed: 2.4 GHz
Number of Processors: 2
Total Number of Cores: 8
L2 Cache (per Core): 256 KB
L3 Cache (per Processor): 12 MB
Memory: 12 GB

Graphics card: ATI Radeon HD 5870 1024 MB

At the moment, I'm on a 6 year old (mid 2009) Macbook Pro with only 8 GB, 2.8 GHz Core 2 Duo [2 cores only vs your 8] and GeForce 9400M with 256 MB ... an old, underpowered machine - super underpowered compared to yours. And yet, AC 19 launches and opens a template and is ready to work in 90 seconds.

So, there must be something amiss in your installation including possibly permissions. Maybe a network issue? Might you have any networked libraries/etc loading?

Unusual slowness in Mac OS can be caused by a failing HD. If you have a clone of your HD try booting up from that one to see if it is slow there too. If not I would have a backup ready ASAP.

I would suspect a file structure issue or permissions. Do you have many apps that start up when you boot?

On my little Macbook Pro (no SSD) with 8GB RAM and a quad core 2.5Ghz i5 Archicad launches and loads the standard AC19 template in about 40 seconds.

I tend to run a minimal setup and only generally have Safari and Mail open.

Your Mac Pro has a few drive bays, I'd suggest clone you system disk and do a fresh install if the permissions repair doesn't work.

Having looked at the CPU usage monitor while launching AC I only use about 40-50% of one core, so you should not be lacking on the hardware side...
