Since High Sierra 10.13.2, AU settings (here ambience AU freeware), won't remember settings anymore. If you load a song, the plugin will always have the default settings. Strangely after reloading (and changing settings), it seems to be ok, again. Also loading of some plugins now introduces a looooong pause, where no hdd action or cpu action appear.

 

Could be related to Apple's "new" way of managing AUs? There seems to be again a new system service, responsible for validating AUs?

I had this same problem. I had to downgrade the OS just to deal with it.

I would guess it would help, if Taktik would drop backwards compatibility to OSX 10.5. Instead compile against minimum 10.9 or similar. Lot of changes from 10.5->10.9, e.g. drop of carbon etc.

This is *precisely* why I wait soooo long before upgrade my OSX! Lame to hear of this issue, but can't say I'm all that surprised. Every new OSX release causes problems all over the place with music software :(

 

Many thanks for the heads up!

Hi Taktik,

 

I made a testcase xrns for you:

Attached File  testcase3.xrns   6.38KB   5 downloads

 

This song has a ambience AU on the "guitar" send track. It loads correctly in Renoise 3.1.1 under macos 10.12.6 (with all recent patches), but loads the default setting under macos 10.13.2:

macos 10.13.2:

Here is the used ambience au:

Please let me know if I can help with testing e.g. under macos 10.13.2.

This was not meant as feature request, but as a bug report.

I now switched back to Sierra 10.12.6 + HFS again, and it is so much faster. The graphics performance of the recent nvidia web driver is about the same 10.12.6 vs 10.13.2 (final versions), but in Sierra, there are no weird slow downs and lags. Also HFS+ loads and writes many times faster than APFS on a SSD here. The difference is really impressive after you switch back again. I read that Apple has lot of problems since 10.13.0 with their nvidia models (unrelated to Renoise though, since Renoise lacks of a modern GUI base).

BTW. you can upgrade to High Sierra without converting to APFS (I would recommend that highly): After you downloaded the High Sierra.app from Appstore, you exit it. Then you start it from the command line, using the following switches:

/Applications/"Install macOS High Sierra.app"/Contents/Resources/startosinstall --converttoapfs NO --agreetolicense

 Apple still has lot of work to do and let's hope they will manage to fix this (does not seem like this):

 

- nVidia mac users suffering from slowdowns over time, reported many times in mac forums

- AMD mac users suffering from slowdowns over time, reported in mac forums

- nVidia mac users suffering from lags and micro freezes, reported many times in mac forums

- Lot of slowdowns in common apps
- The performance loss caused by Spectre and Meltdown patches seem to be quite extreme, and more patches are following in 10.13.3. Let's hope apple will optimize a lot more.
 
Btw. Microsoft now uses other CPU instructions for CPU prediction, and this only works starting Sky Lake. That means the performance loss is more heavy already on Haswell (even it supports PCID).
 
Here is some interesting reading:

Full transparency @ Apple, as always. Mac users are too dumb for such a checker tool.
