When using the last two major releases of macOS ( and ) while opening certain 'older' apps you may have noticed a warning to the effect that they will soon cease to run. You'll see the version of macOS displayed. To check which version of macOS you have, and also the 'gateway' to begin checking many other features of your system:Ĭlick About This Mac (under the Apple logo at top left): They only list the unreliable Apple AirPrint driver, which prevents accurate printing with Application Colour Management. Indeed you shouldn't buy a printer without first checking from the manufacturer's Support site that they have a printer driver for your OS version! Some manufacturers, such as Canon, do not have macOS drivers available for certain 'consumer', and probably also older, printers. You shouldn't upgrade your OS until there's a genuine OEM driver (NOT Apple AirPrint!) available! It may work, but possibly won't. To date there haven't been any reliable reports of printing with 'Big Sur'! Indeed, it appears that the printer manufacturers have very few, if any, drivers which officially support it. You are therefore advised to wait a few months for version '.2' or '.3' at least before upgrading, and to switch off automatic updates! Big Sur and Printing You are advised to check user forums for those apps before upgrading to 'Big Sur'!

The initial release of 'Catalina' was known to be problematic with some applications, and not just those using bit addressing, but high-sophisticated professional apps such as Capture One Pro. 'Mojave' had a whole series of bugs which were only discovered by actual normal users AFTER they upgraded to it. These new versions of macOS are introduced annually regardless of whether or not they have bugs! The users get to test them for Apple. We look at some of its implications, and why you should NEVER automatically upgrade, especially to the first release ('.0') of a new version.įor many years Apple has had a purely-marketing driven policy of annual operating system 'upgrades' which offer very few real advantages, apart from some security improvements and support for newer hardware. Its main purpose is to be compatible with the Apple Silicon ('ARM' based) M1 chips. It offers no compelling new features, but a lot of 'window dressing' with menus, etc. Why You should delay upgrading to ANY NEW version of macOS, especially 'Catalina' and macOS 11 'Big Sur'. This is written with photographers in mind, and you may find more in-depth information and solutions elsewhere.

There's also some advice on Mac 'housekeeping' and why not to rush in and upgrade to the latest version. We explain a few of them here, along with possible fixes or work-arounds. Over the past few years since the release of Apple's macOS 'Mojave' and later macOS 'Catalina' several colour problems were reported by our customers and on internet photographic fora.
