Because continuing to support mixed 32 and 64 bit apps in an OS which is natively 64 bit adds complexity throughout the OS which makes the whole thing slower, bloatier and use more memory and resources. Services, libraries, frameworks all have to support being usable by 32 and 64 bit apps. Apple started the 64 bit transition over 10 years ago, they've warned about compatibility for the last few years, now it's time to reap the benefits of being 64 bit .. before of course someone introduces a 128bit processor and we all do it all over again.

but what does it mean for me the end user?
Will I notice any difference?
I don't notice MacOS now bloaty or slow.

You do not need this. Just click on the Apple symbol in the upper left of the screen then About This Mac / System Report / Software / Applications
There all Apps are listed and you can sort for 64-Bit all others are 32-Bit and will not work after update...

This doesn’t address my point. I know that, and you know that, but the average user does not. That’s what the problem is, IMO.

thats actually a great tip! but sorry to see some apps I have are 32-bit, mostly games. Infact, the Steam client itself is 32bit

Dont worry about Catalina anyway. You already got the two biggest recent Mac OS changes in Mojave: APFS and dark mode. Catalina is minor tweaks compared to those two changes (one under the hood, the other UI related)

really hope the iMac Pro isn't prevented from using the new video features

Footnote 2. 4K, 4K HDR, 4K Dolby Vision, Dolby Atmos, and HDR10 content is available on all Mac models introduced in 2018 or later with 4K-resolution screens.
 
Screen Time is a big one for me. It always seemed kind of pointless if you couldn't track your usage across all of your devices. Now you'll be able to.
 
The question is, how do we manage regular playlists on something like the 4th generation iPod shuffle via Finder?
How about smart playlists on iPhones?
It's possible that you can see all of your playlists in the Finder sync settings, or drag them from Music into Finder.
 
Can someone test & answer the following? Will previously downloaded iTunes content (i.e movies, music, and TV shoes) be automatically transferred over into these apps?

I have slow rural internet and it took months to download my iTunes library of 350+ movies. The thought of having to re-download is a nightmare.

From everything that I've read, it seems like this Music app is just the music playing part of iTunes renamed. it is cleaned up and all the other cruft like videos, podcasts, syncing and what not were trimmed away. It supports the same views, the same lists, the same queries, the same applescripts. I don't think there will neeed to be any transferring of your music content.

Reports are that your movies and podcasts will also be available in their respective new apps.

It looks the same as before.

That's not true. The only downside to supporting 32-bit apps is that you need 32-bit libraries. It has no effect on the speed or memory usage.


If you are a developer please let me know what you are working on. I will make sure I won’t buy any of your stuff.
 
With regards to HDR support on 4K. Can someone confirm whether this is possible via HDMI? I have the latest Mac mini, connected to a 4K HDR TV (SONY AF8 OLED), but so far couldn’t pass HDR because of the OS limitation and the HDMI not being 2.0a (it’s 2.0). Can someone confirm that this OS version is addressing this point, and you can enjoy 4K on HDR in an external TV via HDMI?
 
Is the Console application still crippled as it has been since 10.12 Sierra?

"I suspect that the previewers and reviewers never actually tried to do anything purposeful using Console 1.0."

I would be very interested in a small feature concerning Apple Notes. Does Catalina add the option to export notes in a way different than pdf (most probably in the "File" menu)? Currently it is not possible to export and then again import notes in an usable way without loosing a lot of information or without a lot of manual work involved.

As to dropping 32-bit support, that is likely for the reason that Apple dropped PowerPC support some time earlier. Apple had run PowerPC code in an emulator, and it also had separate PowerPC versions of its libraries. Though Intel's chips can run 32-bit code, Apple still has to maintain 32-bit versions of its libraries for supporting 32-bit code.

As to converting to ARM, will Apple be using a x86 emulator? That is what Apple did with 68K-to-PPC and PPC-to-Intel.
 
Under Tim Cook, all the latest MacOS updates have been bean counter updates, which machines to not support to encourage new Mac sales while offering less and less new features while deleting old ones willy nilly. so now I have to get rid of all my 32 bit apps for nor particular reason? I think not. It's about time that people stand up to this computer authoritarianism.

I mean, I don't think any of my Mac games are 64 bit. I'm not throwing away stuff I paid for just because Timmy thinks it's a great new feature. I didn't like it when Steve Jobs did it either, but he always had something cool enough to weigh in favor or it. Not so with bean counter Timmy. :(

I don't think you understand, at all, what the 64 bit transition is all about. This began almost a decade ago as a way to phase out older inefficient 32 bit apps, so that their equivalent power-intensive 64 bit counterparts can make better, more efficient use of the 64 bit processors that are the standard.

Hanging on to apps because there's a 32 bit version available is like saying you're hanging on to a stained shirt because your identical unstained shirt is new but not the same. Now if you said you use a photo editing app as a career that the developer hasn't updated and abandoned altogether in 2010 is another moot point, because using abandoned software is foolish in itself. You'd be begging to be left behind the longer you keep it alive.

Most good applications would have already had a 64 bit version of the same thing available if the company or developer cared to future-proof their own tech. There's no way you can blame this on Apple, again, who's been warning you for like 10 years that 32 bit apps will soon be dead. The fact they've lasted this long is amazing (and dumb). There's not one app on my system that's 32 bit that I would miss. 4 minor ones (all Apple) actually include 2 called 'before you use iLife / iWork'. You should check yours (via system report) before making that oddball argument.

Just because you know Timmy was predicting it does not mean you liked it or approved or agreed. I think this will be one of the the most poorly accepted MacOS update in decades. We'll see who's right. :D

To your original point; this isn't a beancounter move, it's an Intel move. Hell, it's a technological foot-on-the-ground forward for all computing. You want modern tech? You want a nice machine? You get a modern Mac with a 64 bit Intel processor. If you don't use legacy hardware or old applications, you have literally no reason to complain.

Not to mention, most Macs that got High Sierra will be getting Catalina. These are basically all the same machines that got the initial Sierra. Apple's backwards compatibility game lately has been wildly stronger than ever (see iOS, too).

You're acting like this is just Apple. I don't understand that a bit. There soon won't be any new 32 bit hardware new from any vendors. What will you do then? Blame technological advancement at HP and Dell on Tim Cook, too?

* Of note!! - I sometimes interchange 'you' as the proverbial you; the grand we, everyone and anyone. 32 bit apps aren't the future, and we've all known this since like 2008. For anyone remotely techy to claim they don't is just bring obliviously glib.

** Specifically you... - Here's hoping this incredible, misinformed bias doesn't transfer doesn't transfer over to whatever blog you write. While your opinion is your own, all of your points here are just plain wrong. Even after you admit you may not have anything 32 bit to start with...

Could someone that has Catalina running maybe shed some light on this question? Thanks guys

What good would that do? I make sure all my programs are 64-bit, but sometimes there's an old app or two that the developer hasn't updated in years. I don't know about you, but I'd prefer to use those apps in my workflow at the expense of a bit of disk space. 32-bit doesn't come with a performance hit, i don't know where people are getting this idea on this thread about that. All 64-bit CPU are designed to be backwards compatible, which is a good thing, especially when you need to run software you paid for a long time ago which since hasn't been updated.
 
This is what I could find on Catalina and OpenGL.

Emulator Issues #11755: macOS Catalina Developer Beta - Vulkan backend corrupted graphics - Emulator - Dolphin Issue tracker
Dolphin Emulator on macOS Catalina works with OpenGL but not with MoltenVK. This happens regardless of what aspect ratio and whether set to render main window. The emulator will crash after the Wii safety warning and sideways holding instruction.

So OpenGL still works.

As to MoltenVK, it is: KhronosGroup/MoltenVK: MoltenVK is an implementation of the high-performance, industry-standard Vulkan graphics and compute API, that runs on Apple's Metal graphics framework, bringing Vulkan to iOS and macOS. -- linking to its github archive of its source code.
 
Finally, 4K iTunes media on our 4K and 5K displays. Took long enough!!

This is the feature I’m most looking forward to. I can’t believe it’s not getting more press.

That's a biggie for me but doesn't look to be implemented in the Betas yet. I wonder if it will be possible to stream 4k content to Apple TV 4K?

Thank you for this feedback!

I was going to use the public beta tonight to watch iTunes 4K movies, but not now.

Your Apple TV 4K already streams 4K---are you referring to routing the Apple TV through the iMac?

Can't use the iMac in target display mode---maybe you can airplay from your Apple TV to your iMac---usually goes the other way and I've never tried it, but something to consider.
 
I played around with it for a few days and Catalina looks promising. From a technological standpoint it's the new Snow Leopard. Lots of new Frameworks, Libraries and features build for the feature with a lot of legacy removed (32-bit, QTKit). *

I don't get why they brought iDevice syncing to the finder and didn't include it in a separate app. Now the finder is getting bloated. The Finder is an app for accessing files on your file system. About the only thing you don't do on an iDevice is.... right.

I would also like to see IDevice in it's own app. Maybe next year?

But does that finally mean that you will get 4K HDR via HDMI?
