soooo… any update on display cal for M1 macs?

[kofman13]

So when M1 macs came out, displaycal didnt really work on M1 Macs, displays wouldnt be recognized in display cal. a month later i cant find any thing about new updates. are there any plans for M1 macs in this regard? i feel like it should be important since in 2-3 years all macs will be M1 macs.

I don’t have an M1 mac. Does ArgyllCMS work on it? If not, then it needs updating.

The initial problem seems to be that DisplayCAL does not recognize the monitor.

Not sure if that is an issue with ArgyllCMS or not, but we can’t get further into the calibration process than launching DispayCAL

[Florian Höch]

Test it then. Does dispcal -? give you a list of displays and instruments or not?

[KR Lancaster]

I confess I am not an expert with DisplayCAL nor ArgyllCMS, or the inner workings of MacOS or code in general

Is dispcal -? a terminal command? I will check if you help me through it

[Florian Höch]

Yes, run it in Terminal.

cd ~/Library/Application Support/Argyll_V2.1.2/bin
dispcal -?

[KR Lancaster]

I’m seeing this:

 ** No displays found **

[Florian Höch]

Ok, so ArgyllCMS would need an update.

[KR Lancaster]

Thanks for your help narrowing that down

Does anyone know if Graeme Gill is still actively maintaining ArgyllCMS or how responsive he is? Just wondering if it will be awhile, if I need to start looking at other solutions. Would happily donate to his efforts if he’s working on it

I just found this in the Argyll CMS support threads:

Hi,

I am just trying to run Argyll on a new MacBook M1 2020.
Always get the error message “No displays found”.

that’s sad 🙁

Graeme’s response:

I guess Apple have once again changed/deprecated API’s, wrecking
compatibility with existing applications. Or maybe Rosetta 2 doesn’t
work that well. I don’t have an M1 (nor am I likely to get access to one
any time soon), so it might be difficult to fix. Best bet would be at
least to gather a -D8 debug log and email it to me, to see if there is
anything obvious in there.

Cheers,
Graeme Gill.

Xrite and spyder themselves having trouble too, they say expected compatibility for M1 is Q1 2021…

so we cannot calibrate the m1 MacBook Pro at all then as of now? I have a yellow tint on mine and yes True Tone is off. My 2016 Touch Bar mb pro has a better display and I am extremely disappointed. May just end up returning it if Im downgrading display which is sad

I cannot get my Mac Mini (late 2012) to find any displays.  I am on Mac OS 10.15.7 (19H114) .  My Argyll is in a different path ~/Library/Application Support/DisplayCal/dl/Argyll_v2.1.2/Bin ) this is where DisplayCal downloaded and installed it.  I run the dispcal -? the -? does not seem to be a valid argument.

bin % ./dispcal -D

get_a_display called with ix 0

Found 3 screens

CGDisplayIOServicePort returned error

dispcal: Error – Unable to open the default display

But DisplayCal does not show any of my 3 displays.  One is displayport, one HMDI and one is USB to HDMI (displaylink chipset).  I have calibrated with DisplayCal before, but I cannot today.  I have uninstalled and re-installed.

NOTE: move this if it should be in another thread

If you need to calibrate an external display, I found a workaround that works on M1 Macs: https://hub.displaycal.net/forums/topic/displaycal-and-big-sur-on-m1/#post-27658

[Hotp]

I’m new to DisplayCal, but note that for Apple M1 and Big Sur it does not recognize external monitors.

So can I connect the external monitor to my existing Intel iMac, calibrate it, and then attach the monitor to the M1 Mac, and somehow take the calibration-definition from the older iMac, and use it on the new M1 Mac?

How is that done? (no experience with DisplayCal)
