HighSierra will stop some of your Apps…

Just read on some other website, you should check your apps if 64bit-compatible.

You do so, by clicking /about this Mac/System Report
Then, left column Software/Applications, lists all your installed apps …
check each, and in the Zoom Window its
64-Bit/Intel Yes

… or no.…

My finds contain…
• surprisingly: DVDplayer.app (from Apple - so, although Cupertino doesn't like spinning disks, I hope a software-player is included in HS)
• iDVD… ohooh... (for those rare occasions, I keep a clone of an older OS to launch from)
• some 'service tools' from coremelt…
• and iMediaHUD - a tool I found handy for analyzing media-files. (that is a pitty!)

DVD Player comes with the OS and is system protected.

Apple's Compressor is not 64 bit so I guess that will be updated before High Sierra comes out in the Fall.

How do you tell if an app is 64-bit?

HS will be the last OS to accept 32-bit apps I understand,

What Karsten said about looking up in About This Mac, System Report/Applications

Man, I have LOTS of Apps that are not 64 bit according to system report, including Microsoft Office 14.7.5, Adobe CS 6 Dreamweaver, Illustrator, Band in a Box 2015, Bento, Final Cut Pro 7, and a bunch of others.

As usual, I'll wait for the xx.3 version of HS before going near that!

Thanks. Missed that. Sorry.

… hm, 'before', …?

Ferenghi promised all kind of video marvel with macHighSierra, such as h265, and - please correct me, if I'm wrong - the new chips in use in 2017 Macs support hardware-accelerated encoding and stuff … << I'm not the hardware guy.-

… recently, someone posted his BruceX results from a nMBptb (<<< I LOVE those abrv. :blink: ) - it's now super-fast, what if encoding is optimized any further!?

How I understand it, macSierra is last 32bit and macHS is 64bit only…
Anyhow, my 5y old mini is still supported … for an hobbyist an awesome return-of-investment.
(… btw: anyone offering a used, 2012=stone-old, obsolete, practically unusable 5k iMac soon? )

"At WWDC Monday, Apple announced that this year’s macOS High Sierra will be the last macOS release to support 32-bit apps “without compromises.” Starting in January 2018, all new apps submitted to the Mac App Store must be 64-bit capable and, as of June 2018, both new apps and app updates must be 64-bit capable. Submissions not matching these requirements will be rejected as a matter of course.

I have heard that if you are running Sierra now, High Sierra should work fine with all currently functioning applications. Can't remember the source though.

Tom, You beat me to it!

I guess no one here is a Developer, as they can already play around with the betas.
I participate in the public beta program so by end of this month, I will get the betas and can then give further info about HS...

Two biggies are going to be MPEG Streamclip and QuickTime Player 7.

I'm running developer beta of HS, but been very busy with paying work. Will start launching apps and see.

I've been told by Coremelt they don't test their plugins until the public release version is out, and then they will update all their plugins quickly.

NEVER upGRADE an OS until all your apps and plugins catch up. And for various reasons, that is NOT the day the upGRADED OS is released.

So we'll just play it by ear.

Apple's software will have upGRADES to be compatible with HS after the public version of HS is released. How soon? We'll just have to play it by ear. And I'm sure Compressor will have a 64-bit upgrade.

I'm very surprised Adobe apps are not 64-bit already.

FYI, Compressor is a 64-bit app that still supports 32-bit codecs. Tricks have to be pulled to let 32-bit codecs run on a 64-bit system. The System Profiler isn't accurate with these types of mixed things.

Proof; I just encoded 6 files, different original formats, to different transcodes, with current version of Compressor in developer beta of High Sierra, seems pretty stable and swift, too.

High Sierra won't stop anything. The next macOS version *after* High Sierra will.

macOS is a year behind iOS on this front, as iOS 11 *will* stop older 32-bit apps from even launching. It's a line in the sand for some important apps, including the installer for Adobe CS6, FCP 7 and more.

My inside information tells me that High Sierra and iOS 11 with both indeed NOT run 32-bit apps. And that Compressor is a 64-bit app. I'd be surprised my info was wrong.

Do we have documentation of HS running or not running 32-bit apps?

Nope, your inside info is incorrect, High Sierra WILL absolutely run 32-bit apps. Apple are on record (during their State of the Union presentation) as saying that macOS High Sierra will be the "last macOS release to support 32-bit apps without compromises." There will likely be a warning on launch of a 32-bit app, like there has been on iOS 10.3 prior to the release of iOS 11.

Additionally, as of January 2018, new 32-bit apps can't be submitted to the Mac App Store. No updates after June 2018. But the major problems for video editors is going to be old non-Mac App Store apps.

High Sierra will be fine. The one after High Sierra (Modesto? Big Sur? Golden Gate?) will be the one to stop older apps running.

System info lists the current version of Compressor as not 64-bit. I think this is because QuickTime still retains some 32-bit codecs.
