New OS releases drop support for older devices

New OS releases mean that some of older devices are left behind. This is true for iOS 16, watchOS 9, macOS 13 Ventura.

iOS 16 will not be available for iPhone 6s, iPhone 7 and original iPhone SE.

iPadOS 16 will be provided for:

  • iPad Pro
  • iPad Air (3rd generation and later)
  • iPad (5th generation and later)
  • iPad mini (5th generation and later)

watchOS 9 leaves Apple Watch Series 3 behind. Which is a bit strange since Series 3 are still sold by Apple as entry-level model.

macOS 13 Ventura also drops support for several older Macs. Currently supported are:

  • iMac (2017 and later)
  • ‌iMac‌ Pro
  • MacBook Air (2018 and later)
  • MacBook Pro (2017 and later)
  • Mac Pro (2019 and later)
  • Mac mini (2018 and later)
  • MacBook (2017 and later)


watchOS 8.3 might have issues causing problems with third party chargers

Some Apple Watch 7 users report problems with charging using third party chargers after upgrading to watchOS 8.3.

Updated my watch last night to 8.3, set it on my 3rd party charger this morning, came back after an hour and it had gained maybe 2%?
Tried the same thing with my spouse’s watch and her 3rd party charger with the same result.
Put them on the official charger, zoom, done charging in no time. Argh!

New round of beta versions is here

Apple publishes iOS 15.1, iPadOS 15.1, tvOS 15.1 and watchOS 8.1 beta 2. macOS 12 Monterey beta 8 is also released.

Interestingly, no corresponding Xcode beta is published.

Notable changes include:

  • SharePlay is now re-enabled;
  • Unlock with Apple Watch is now working again for FaceID iPhones;
  • Lossless Audio and Dolby Atmos with Spatial Audio support to the ‌HomePod‌ and HomePod mini;
  • macOS 12 Monterey shows signs of "High Power Mode", which should provide more performance in exchange for smaller battery life.

New study puts Apple Watch Series 6 oxygen sensor on the same level as hospital equipment

Study conducted by University of São Paulo compared Apple Watch Series 6 with commercial oximeter devices. Results show that oxygen saturation and heart rate reported by Apple Watch are on par with typical industry devices.

Comparison of SpO2 and heart rate values on Apple Watch and conventional commercial oximeters devices in patients with lung disease

Our results indicate that Apple Watch 6 is a reliable way to obtain heart rate and SpO2 in patients with lung diseases under controlled conditions. The advance of smartwatch technology continues to improve and studies to assess accuracy and reliability in various types of disease should be carried out.
