Affinity photo 1.73 released for mac.

Hi there is a new release of affinity photo 1.73 as well as designer and publisher.
This release includes enhanced support for 'sidecar' in catalina. However not all macs will support sidecar.
A lot of intel procesors feature hardware video encoders known as quick sync. Ivybridge processors had h264 encoding. Apple used this for Airplay so you could extend your desktop to say an apple TV or mirror your desktop display. Basically your desktop and windows were composited to a h264 video stream which was decoded on the recieving device. Best of all it was essentially free as it didn't use gpu or cpu cycles for doing this as it was a seperate bit of silicon on the CPU die.
Airparrot was a third party solution which did the same thing only with a software encoder.
Duet display works similarly but uses the iPad as a screen. And then Apple made Sidecar. Its fairly similar in practice to duet but it uses quick sync for hardware encoding to h265 video. This has about twice the compression of h264 which makes it possible to update faster and support higher resolutions.
The problem for older macs is the CPU doesn't support h265 hardware encoding, it needs a skylake processor as a minimum.
On the plus side duet still works on catalina and the maximise button has been extended to as well as maximise it can set an app to half screen verically split or send the app to another screen , e.g iPad. So far duet isn't supporting the new sidebar in sidecar but you can have the macs touchbar , even if you don't have it on your mac.
What makes this of interest really is apple pencil which makes it quite easy to work with dodging and burning directly on the iPad but using the desktop app. The pencil works on iPads from 2018 as well as the iPad Pro
I hope this has been of interest.

Yes but only from the perspective of a user of Luminar that I have had the pleasure of running a beta version of L4 on my older ( 2014 ) Mac and it runs fine.

Thank you for the heads' up. I've passed the word along to my friends here.

unfortunately, a lot of pp software is relying on newer machines. Probably not as much a problem for the pc users as they tend to replace their machines more often than mac users. I am using a mid-2011 27 inch iMac that runs great but some software is relying on newer hardware to run. So far my prime software apps run great on my machine like on1 2020, Topaz Studio 2 and Flex but with the release of Catalina as the current macOS is now 2 versions back because of the graphics change macOS made in high sierra and continued in Catalina. As soon as something I need won't work then I will be upgrading but I figure 8 plus years is a pretty good TCO. Our work pcs (in the hundreds of thousands) only last 2 years before having to be replaced. My company is now allowing macs instead and showing a TCO 1/10th of the cost of a pc. Same for IBM and others.

Its worth baring in mind that you can easily run different versions of OSX via USB, firewire esata and thunderbolt. or even target disk mode.
I'm running el capitan on the internal drive of my macbook pro I have catalina on an SSD connected via esata and thunderbolt.
If you google dosdude and catalina say you can find he has apps that can create installers on unsupported macs, although catalina needs a metal compatible graphics card. integrated that means ivy bridge or newer but for mac pros you can find compatible graphics cards.
