Wonder if the first build is stable or very buggy

It has been incredibly stable on all of my devices. I installed yesterday right after the event and I have not put my 16 Pro Max on the charger since and it is still at 65%.

Yeah I see that in mine as well there is no developer option there anymore I wonder how they will fix it

I had the same message and assumed the servers would be overloaded. Today, the message didn’t appear and the „Beta Updates“ option returned.

Yeah, I was wondering about that. I charged it to 86% then went outside mowed for four hours while listening to music and it didn’t drop at all when I got done after four hours. It was still at 86% so I’m not sure if the battery indicator is working correctly or what. My Ultra Gen 1 went from 100% to 63% during the same time frame.

Yeah I just saw that thanks
They must have fixed it

Stable. Same as Sequoia so take that was you will. There aren’t any real changes outside of UIkit being remodelled. Outside of graphical bugs with the kit itself, everything works just as well as Sequoia.

feel like a reskinned Sequoia so far, it’s nice, some weird choices here and there, but seems like a sequoia update, not complaining, just happy is stable.

Who’s gonna show us the looks of the iOS 26 Books app? Much appreciated!

It pretty much looks exactly like iOS 18 except with the new button style

so u go in terminal

Code:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-16beta-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1|InstallInfo.plist)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
    curl -# $file | egrep -EA 1 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
    echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

Small fix:

Code:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-16beta-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

thanks. it's cleaner but unfortunately doesn't show osversion number

here is a further improvement which also shows version number

Code:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-16beta-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 3 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

so all i did there was replace your -m 2 with -m 3

Apple seems to be on a mission to reduce users screen time at any cost. This IOS is not just repellant, it is functionally at odds with their design language.

It is working just fine, I was at 90 something percent when I installed.

so all i did there was replace your -m 2 with -m 3

It does show OS version. -m3 returns Build twice.

oh

but this what i got

so i think i'll still use the -m 3 instead

dunno why the -m 2 works for you and not me

but anyway it's still cleaner than what i had before so thanks

Thank you for the screenshots! Looks like Apple still has a lot of work to do for the experience, for example making the books in ‘continue’ way bigger than those small tiles.

Geez... 16GB. We've come a long way. How much storage did we have on the first iPhones?

I have an old iPad mini 2, that I still occasionaly use to read books and watch Netflix. it has a total of 16 GB. Albeit, I can't run anything past 12.5.7 🤷‍♂️

My days of dropping early betas on the daily driver are over. I’ll see you in late August.

Welcome to early middle age, where we like things to remain relatively predictable. Come on in, there’s plenty of room. 😌

I know there's a lot of complaints on these boards, but I swear my iPhone 16 and M1 MBA are running as fast as ever, maybe faster.

Same here..there are bugs, but don’t seem any more than public beta when it comes out. Jury is out on battery drain though

ksgant · Jun 14, 2025

Running iPadOS 26 on my M4 iPad Pro. and so far it's been great. Love the new features. And I'm amazed that there wasn't any hit on the battery life...at least so far. And it's been very stable and smooth.

watrobkasmaczna · Jun 15, 2025

I get Windows Vista vibe with the look of MacOs Tahoe

MacRumors said:
Apple today provided developers with the first betas of the new iOS 26, iPadOS 26, macOS 26 Tahoe, watchOS 26, tvOS 26, and visionOS 26 betas for testing purposes.

Registered developers can download the new beta software through the Settings app on each device.

Apple's software updates include many of the new features that were shown off at today's keynote event, with Apple rolling out a new Liquid Glass design aesthetic across all of its operating systems. You might also notice that Apple has changed the way that it numbers its updates, bringing more cohesion to the lineup.

There are a slew of new features to go through, so stay tuned to MacRumors in the coming weeks for hands-on footage, guides, how tos, and an in-depth look at everything you'll want to know about the new updates.

While today's betas are designed solely for developers to give them time to learn the new features and adjust their apps, Apple will provide public beta testers with a chance to try the software in July. iOS 26, iPadOS 26, macOS 26, tvOS 26, watchOS 26, and visionOS 26 are set to launch to the public in September.

The Beta is great so far... I am unimpressed by the glass theme overlay on backgrounds and images Control Center and some functions like widgets on the home screen are impossible to read

OlliFlamme · Jun 18, 2025

Ugh, I don't like the glass stuff AT ALL.
Does it have 'reduce transparency'?
Dark mode any better than this sea of see-through?
Sorry, this may be the first time I am really not tempted

Synthetic · Jun 19, 2025

I am not having as much luck on my 15 Pro Max. Bad battery performance, some apps like Amazon make it feel like I could cook an egg on the phone, sometimes my space bar disappears, and all sorts of other issues. Thinking about resetting the phone back to factory to see what might happen.

replace the 16 with 26 u get nothing

actually you do now

these are a thing now

Code:

https://swscan.apple.com/content/catalogs/others/index-26-1.sucatalog

https://swscan.apple.com/content/catalogs/others/index-26seed-1.sucatalog

https://swscan.apple.com/content/catalogs/others/index-26beta-1.sucatalog

https://swscan.apple.com/content/catalogs/others/index-26customerseed-1.sucatalog

but so far only these 2 have stuff in them

Code:

https://swscan.apple.com/content/catalogs/others/index-26seed-1.sucatalog

https://swscan.apple.com/content/catalogs/others/index-26customerseed-1.sucatalog

so if you run this:

Code:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-26seed-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

you get the link for the beta 2 full installer

Code:

            Build
            25A5295e

Bookmarks are fixed on iPads OS thankfully. That was causing me major issues.
