15.4 was supposed to be my target build to upgrade from Sonoma, but after witnessing the Apple Idiocy debacle, I think I'll skip Sequoia altogether
Humans are odd creatures.

We've always known that Apple was playing the long game with AI integration work, and there was a chance that timelines would be stretched as they pushed forward.

Apple Intelligence hasn't been a failure. I, for one, appreciate that Apple is committed to a great experience, and is taking their time.

The day will come when Apple's implementation is the industry standard, and other companies will want to mimick it. Have patience.

In the meantime, your Mac gives access to all competitor solutions today. Interesting, eh? 😎

Build 24E248, or one higher than the second RC.
here are the builds of the other stuff released today:

macOS 14.7.5 (23H527)
macOS 13.7.5 (22H527)
iOS 18.4 (22E240)
iPadOS 18.4 (22E240)
tvOS 18.4 (22L255)
audioOS 18.4 (22L255)

iOS 15.8.4 (19H390)
iPadOS 15.8.4 (19H390)
watchOS 11.4 (22T251) - pulled and re-released next day

for the build 24E248 of macOS Sequoia 15.4 here are the ipsw and full installer:

ipsw: https://updates.cdn-apple.com/2025SpringFCS/fullrestores/082-16517/AACDDC33-9683-4431-98AF-F04EF7C15EE3/UniversalMac_15.4_24E248_Restore.ipsw

full installer: https://swcdn.apple.com/content/downloads/43/58/082-16524-A_VHRNGIT194/ksdv19dcxx90ja7nronzpb4kr4val0imsz/InstallAssistant.pkg

here are the full installers for Ventura 13.7.5 and Sonoma 14.7.5

macOS Ventura 13.7.5 build 22H527: https://swcdn.apple.com/content/downloads/61/08/082-11327-A_JKF2NNDDY8/aaxgevztdm1i5v6q6xousfc44xa90ykmk0/InstallAssistant.pkg

macOS Sonoma 14.7.5 build 23H527: https://swcdn.apple.com/content/downloads/40/16/082-11498-A_J7T1GLHFVZ/chr3rxmbukm8zmyun90r1gz1wodsaeuzda/InstallAssistant.pkg

easy to confirm builds for ipsw as build is in the link but you can also find it in terminal by running this:

curl https://mesu.apple.com/assets/macos/com_apple_macOSIPSW/com_apple_macOSIPSW.xml | grep ipsw | sort -u | sed 's/<string>//g' | sed 's/<\/string>//g' | grep -v protected

There are 2 ways to confirm build for the full installers

Method 1 - download the pkm file

I use the sequoia one as example

Replace the g with a m at end of link, i.e.,

https://swcdn.apple.com/content/downloads/43/58/082-16524-A_VHRNGIT194/ksdv19dcxx90ja7nronzpb4kr4val0imsz/InstallAssistant.pkm

download pkm file and open with textedit

you see this:...version="24.4.248"...

how to read build number: second number 0,1,2,... is A,B,C,... so the 4 is E and build is 24E248

(note if it were a non-rc beta there would be a fourth number 1,2,3,... which is a,b,c,... so for example 24.4.5238.1 is build 24E5238a)

Method 2 - reveal the link in terminal

To reveal links in terminal, which also shows builds

Sequoia:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-15-1.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

Sonoma:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-14-1.sucatalog | grep Info.plist | grep -Evw '(Info.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/Info.plist/InstallAssistant.pkg/g"
done

Ventura:

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-13-1.sucatalog | grep Info.plist | grep -Evw '(Info.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/Info.plist/InstallAssistant.pkg/g"
done

several builds may be revealed but the most recent one would be at the bottom of the list, so again using the sequoia one as example we see this at the bottom of the list:

Build
24E248
--
OSVersion
15.4
https://swcdn.apple.com/content/downloads/43/58/082-16524-A_VHRNGIT194/ksdv19dcxx90ja7nronzpb4kr4val0imsz/InstallAssistant.pkg

note if you use the method 2 for betas, replace sucatalog index with the following

index-15 becomes index-15seed, index-14 becomes index-14seed, index-13 becomes index-13seed

Why does everyone have the need to post their individual hardware when saying they haven't been pushed a software update, yet? LOL!
Different hardware has (slightly) different update builds and some get pushed earlier than others.
