I can recommend to everybody to listen to an excellent Bitcoin Review podcast number 048 (https://podcasts.apple.com/ru/podcast/bitcoin-review-podcast-with-nvk-guests/id1632017958?i=1000626497420) on this topic (this podcast should be listened to everyone in the space, because it's a bunch of devs talking about software and hardware updates).

I personally have found Lume nostr client (https://lume.nu/) which works on Intel Macs through it (multiple other Nostr clients only work on newer M1/M2 Macs).

On iOS Damus is OK (and probably Primal, but it needs newer iPhone, my whole device park is quite retro at this point).

In browser Snort is buggy, but functional right now.
