Although I can load DisplayCal, when I try and use it the MAC (Pro late 2013) intervenes and says the software is from an unidentified software developer. In System preferences I sometimes under Security and Privacy have the option to ‘ignore and open anyway’. When I do this and try and use DisplayCal the Mac intervenes with the cancel/close software notice. Can anyone help please?
Look in System preferences and find Security & Privacy. If you have that open when DisplayCAL loads you will see the OS “complain” about a number of components. At each alert, go to Security & Privacy and it should give you a chance to allow those software components to run. Then select Cancel in the alert. It will move on to the next one. Do the same. At some point you will get a new alert asking if you want each of those apps to be allowed to run. Allow again and you should be ok. Note that it will bump into this again as it tries to create the profile and you will lose the time spent doing the first measurements, so plan ahead with your time.
Let me know if you have further questions.
Thank you Timmah. By following your procedure I finally managed to calibrate my monitor with 3.8.9.3 on my Mac Pro late 2013. I am trying to decide if I need a new monitor as mine is quite old but hasn’t had a lot of use. Can I ask you if the graphics card being used with a monitor has an effect on the calibration? If I change my monitor I’m not convinced that fancy displays for proffesionsal say photography use with built in calibrators are worth the money over a very goof generic monitor?
I am glad that the procedure worked for you. I am not an expert on the technology side of things, just an advanced amateur photographer who is fussy about color fidelity. I have NEC and Eizo monitors that are 12 and 16 years old that were very expensive at the time and they were distinctly better than what was commonly available back then.
With some life changes, those were in storage and I have been mostly using my 2017 MacBook Pro and added a decent quality, but not pro, external monitor about eight years ago. I have found that with decent calibration the results I get are acceptable. It seems that newer monitors are even better.
I only print occasionally and feel like having a high-quality printer and quality paper makes the most difference. I have an Epson 3880 and a canon pro 100 that both produce good results on good paper if I mind the color management properly.
One of the most challenging things in today’s environment, in my experience, is that people are mostly viewing images electronically, and they are viewing them on a wide variety of devices and in different applications, all of which have an effect on the fidelity. With that, I have become Less fussy about precise color rendition and more focused on overall presentation and effect, if that makes sense.
That is my experience and if you kick in an extra five dollars, you can get a cup of coffee for it. I’m sure there are people with more expertise that can offer more sophisticated counsel.
After I managed to calibrate my old Dell monitor – 10 years old – I compared the colour gamut of the profile to those of SRGB and Adobe RGB – see diagram where I overlaid the colour gamut maps. My Dell monitor see 93% of Adobe RGB and all of SRGB so I wonder if I need to replace it after all ?
Thats only the very small part of the edges of the color system. Your eyes judge it better by look at primary color levels and see if all primary colors are even on brightness. http://www.lagom.nl/lcd-test/contrast.php . You can tell by the skin tone colors too. If you can not make it look right it is bad.

Unrelated to sensible replacement policy. Take a look on calibration curves and resulting calibration tracking of true neutral grey (a*b*=0), or contrast depending on your work.

You cannot use that for macOS, it’s almost color managed everywhere and Apple CMM capabilities are limited
I thought browsers are color managed in Windows. It should test good with Mac. I would not use it for calibration. http://www.lagom.nl/lcd-test/display_settings.php#color_management ; They recommended the Safaria browser and give help for mac users and windows.
How it sets your calibration curves is just looking for very uneven curves. The tracking of grey is a good test. The tracking of color is too. You can trust your meter and trust your eyes.
