Not a big market for player or ripping software for Mac Anymore, so we will get older looking interfaces with software just updated (hopefully) to work with the new OS. Bluray still has a market (though apple and others try still to kill it). Still a market in players (non computers) to hook up to TV etc.
Toast (Corel) has come out with barely anything concerning their DVD-Bluray software over the last years and they are to date up to version 18 (I have). Version 17 and 18 is buggy as they attempted to go with all 64-bit and a slightly new interface. I still go back to Toast 11 to do most of my work. Toast 11 is solid with literally no issues. Use it on OS X Yosemite and El Capitan still. I guess technically it should work with Mojave being it is the last to house 32-bit code (though not all 32-bit apps work).
I have been very disappointed with Corel (was a heavy user way back...), as it use to be one of the go-to companies for Graphics back in the day...but with all of the owner and employee turn-overs, they do nothing but put out the same software with minor or really no program Upgrades (just barely adjustments for compatibility) and sell the same offering. Even the interface of their software still looks like the early 90’s. Probably any coders who know the apps are gone, so whomever is their coder now probably does not know what they are looking at and just adjust or add coding for compatibility and sell the same app over and over....
They had great programs in the day...but dropped the ball years ago. Going to the subscription model put the nail in the coffin for many, especially with pathetic upgrades...and the high costs for their suite (combined) apps is a joke now. Don’t care for Adobe anymore as they have chanced too over the years. Other apps out their are good, but Adobe got the industry some years ago, so sometimes a must to play.
