Apple Releases Second Beta of macOS High Sierra 10.13.5 to Public Beta Testers

Apple today released the second beta of an upcoming macOS High Sierra 10.13.5 update to public beta testers, two weeks after seeding the first beta and three weeks after releasing macOS High Sierra 10.13.4. Today's public beta is identical to the second beta provided to developers earlier this week.

Beta testers who have signed up for Apple's beta testing program will be able to download the new macOS High Sierra beta through the Software Update mechanism in the Mac App Store.


Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.

macOS High Sierra 10.13.5 once again introduces support for Messages on iCloud, a feature that was present in macOS High Sierra 10.13.4 betas but pulled ahead of the release of the updated software.

Messages on iCloud is designed to store your iMessages in iCloud for improved syncing. Right now, incoming iMessages will be sent to all devices where you're signed into your Apple ID, but it's not true cloud-based syncing because your old messages don't show up on new devices nor does deleting a message remove it from all of your devices, both features enabled through Messages on iCloud.

The Messages on iCloud feature also allows your older iMessages to be stored in iCloud rather than on your iPhone, iPad or Mac, saving valuable storage space. Older attachments are also stored in iCloud.

No other major outward-facing changes were discovered in the first two developer betas, but the update likely includes bug fixes and improvements to address issues discovered since the release of macOS High Sierra 10.13.4. Because Apple does not provide detailed release notes for macOS High Sierra updates, we may not know exactly what's included until the new software is provided to the public.

If you still haven't updated to High Sierra, DON'T. Sierra was a better OS, and there are no real benefits with High Sierra (unless you want to use an eGPU). It's basically the same system with a new slower file system (vs HFS), startup and overall response is slightly slower, there are various bugs depending upon which Mac model you use etc...etc... The latest 10.13.4 update made things worse, not better (introduced new bugs with both my iMac Pro and MacBook). This is like walking backwards into the future.

I have the latest HS on my mid 2010 mac pro and it is the stablest OS so far for my computer. I was on sierra but I was getting system freezes that multiplied after the security updates. There has not been one system freeze or crash since updating to HS 10.13.4

I'm still on El Capitan on my work laptop, and Sierra on my home laptop.

Am also afraid to upgrade :D

Same here. High Sierra on a 2010 Mac Pro is a rock.
On a 2016 Touchbar MacBook Pro with LG 5K screen, not so much. It crashes a lot.

I still don't get it. I can open multiple PDFs and drag and drop thumbnails of any page to any document and rearrange the oder.

Maybe you needto turn on thumbnails here?


works for me as usual as well

Going from Sierra to High Sierra is technically speaking an upgrade, not an update. It's okay. Lot's of folks use them interchangeably.

It’s crap. 10.13.4 even broke multi display support, and it’s generally quite buggy. If you’re happy with Sierra, I suggest you stick to it.

iCloud Family Shared Storage (High Sierra only) has been a godsend for our Mac laptops which only have 128GB ssd and were perpetually short of space.

Now all our Macs iPhones and iPads are backed by a single cheap shared 2TB of automatically managed online storage and the OS deals with shuffling files and photos around as needed. Saved me hundreds of pounds in not needing to upgrade or buy bigger SSDs or the pain of external drives or having multiple smaller iCloud storage account subscriptions.

If you take into account his correct use of punctuation you'll see that you misinterpreted what he said ;)
He upgraded to HS so that he could unlock with his Apple Watch. That's it.

Yep, you’re right. I read it as he stayed on HFS+ because APFS would have given him a problem with the AW. Thanks for pointing that out! :)

You said HS has been crap. I gave an example of a specific HS-only feature saving me several hundred pounds.


Ok, fair. We have completely different usage scenarios, and I admit I had overlooked this feature.

Speaking from the shoes of a designer working with multiple displays and I/O means, High Sierra (and the new MBP) have offered me nothing but setbacks.

Are people finding High Sierra generally good at this stage? I had a bad experience with the first few builds of High Sierra and haven't tried since. the features didn't seem apparent to me, for the downgrades of bugs and shot battery life.

Im still on 10.12.6 Sierra on my 2016 nTB 13"

can't afford to have a crap OS on my only computer

For the most part, High Sierra is stable for me, but it does eat the battery like a 7 year old at a candy store.
