I'm using Instruments to profile a C program that prints to stdout via printf but the program output does not appear in the Detail Area of the stdout/stderr instrument I added. The program is launched by Instruments itself when I click the Record button and it appears to run correctly – I just can't see the stdout output. I'm using Version 14.3.1 (14E300c) of Instruments on a MacBook Pro 16" (2019) running macOS 13.4 (22F66).

I'm trying to learn about profiling by tracking the events L1D.REPLACEMENT, MEM_LOAD_RETIRED.L2_MISS, and MEM_LOAD_RETIRED.L3_MISS using the CPU Counters instrument in Instruments 14.3.1 (14E300c) on my MacBook Pro 16" (2019) with the Intel Core i9-9980HK, running macOS 13.4 (22F66). In this run, the counters do show some values but they don't change after the first few seconds of the program even though the program ran much longer. In other runs, the Detail Area for the CPU Counters instruments doesn't get populated at all. What am I doing wrong here and how can I get this to work? Thank you for any advice.

On tvOS you can choose Settings > Accessibility > Display > Focus Style > High Contrast to have teasers highlighted by a white border when focused: However, I cannot find out how to use this feature on my own custom views. It seems that only TVPosterView makes use of this High Contrast accessibility setting. I'd like to be able to show such a frame on my custom views if this setting is enabled but I cannot find how to check if it's enabled. None of the bools listed on https://developer.apple.com/documentation/uikit/uiaccessibility under Capabilities (like isVoiceOverRunning, isGuidedAccessEnabled, isReduceTransparencyEnabled, etc.) seems to refer to this Focus Style setting. Can anybody point me in the right direction? How do I check in code whether Focus Style is set to High Contrast? How do I get the High Contrast frame on non-TVPosterView views?

I'm trying to use the Xcode 15.0 beta on macOS 13.4 (22F66) on a MacBook Pro 16" (2019) but whenever I try to start a new project, Xcode becomes unresponsive – seemingly indefinitely. In Activity Monitor I see "Open and Save Panel Service (Xcode) (Not Responding)": Even if I try to use Xcode 14.3.1 now I get the same problem. I've tried to resolve this by removing all Xcode-related files as well as the Xcode command line tools and reinstalling them but to no avail. I'd appreciate any and all help in how to fix this. EDIT: I have since found out that if I force-quit the bird process, Xcode will react again. But the bird process will start up and shoot to the top of the % CPU l column in Activity Monitor again almost instantly. It appears to be iCloud-related but I don't know what's causing it to take up so much CPU resources and make Xcode unresponsive, and how I can fix this.
