1.15.x crushes CPU

[w0x0f]

I’ve been running makemkv for years, and it’s generally been very light on CPU load—maybe a small fraction of one core. It’s very easy to do other compute-intensive activities while 1.14.7 is running.

When I loaded 1.15.1 today, I saw that the load was way, way up; three copies running simultaneously were taking about 400% (so essentially 4 cores). The rest of the system slowed to a crawl.

I rolled back to 1.14.7 and saw the old load behavior—about 65% total for all three copies running.

This is on MacOS 10.11.6, on a 2010 MacPro with 12 3.33GHz cores.

Any ideas why the sudden change in performance?

What were your source disks?

The 1.15.1 version adds features for dealing with Atmos and Dolby Vision disks, which may be contributing to it. I don't have either, so I haven't noticed a significant CPU usage change.

Mac guy myself, I will say 10.11.6 is really really old os. End of Support from Apple was September 2018

With Processor Firmware updates you can run 10.14.6 (Mojave) on that Mac.

10.14.6 supports NVMe drives and you can even put your boot os on it, and get an easy 1400MB-1500MB a sec on it.
Great to have a target drive with an Name drive on it for dumping your MKV files.

I just ran a test of 1.15.1 on an older mac with OSX 10.14.6 and very low core use. No issues, and ran a blu ray on an external case via USB3.2 (using an add on card).

Good luck.

I am having similar issues to w0x0f. Using MakeMKV on my Macbook Pro for years, it's now causing my mac (macOS 10.15.3) to crash with some blu ray discs: Big Lebowski and Frozen. Same description as w0x0f for crashes. MakeMKV version 1.15.1

Any help would be much appreciated.

Thanks for the prompt replies and apologies for not replying sooner.

Upgrading older MacPros (2010 era) includes getting a graphics card that will be acceptable to High Sierra or later. Also, lots of tools that didn't make the jump to High Sierra or later due to deprecation of certain OS functions.

When I wrote "crushes CPU", I should have been more descriptive. I'm not seeing high CPU load, but I am seeing very very sluggish mouse and keyboard activity. The mouse and keyboard are on the native internal USB 2.0 ports; the BDs are on a separate USB 3.1 PCIe card (Sonnet Allegro Pro 3.2 4-port). The lag on the mouse gets worse as additional MakeMKV instances are launched.
