This is probably super simple answer that I missed, but: I have an app that has a database; I'd like to create a second app (actually a CLI tool), and access the same database. Is that possible? And, if so, how? 😄

We have a customer reporting a bunch of problems with our (Transparent Proxy Provider-based) suite. Looking at a sysdiagnose, I see that our GUI applet was killed: Termination Reason: Namespace PORT_SPACE, Code 14123288431434181290 (Limit 305834 ports) Exceeded system-wide per-process Port Limit Looking at the top.txt file from it, I see that it has 193,086 ports -- compared to about ~250 on one of my test systems. Has anyone run into this? Any idea what might be causing it? (I'm still poring over the sysdiagnose, but I don't see any kernel logs around that time -- except that our process does close a dozen or so ports because of cancellation.)

We're trying out using a 3rd party java applet as part of our suite, but we're getting inconsistent results that seem to be related to signing. "Fortunately," I can trivially reproduce it! It pops up a dialogue saying "Apple could not verify “java” is free of malware that may harm your Mac or compromise your privacy"; if I click through the dialogue and the system settings, it then does the same for each of the dylib files. The file seems to be signed, so is this a matter of it not being notarized? Will we have to sign and notarize them all on our own?

I filed FB19631435 about this just now. Basically: starting with 15.6, we've had reports (internally and outternally) that after some period of time, networking fails so badly that it can't even acquire a DHCP lease, and the system needs to be rebooted to fix this. The systems in question all have at least 2 VPN applications installed; ours is a transparent proxy provider, and the affected system also had Crowdstrike's Falcon installed. A customer system reported seemingly identical failures on their systems; they don't have Crowdstrike, but they do have Cyberhaven's. Has anyone else seen somethng like this? Since it seems to involve three different networking extensions, I'm assuming it's due to an interaction between them, not a bug in any individual one. But what do I know? 😄

I spent 20 minutes trying to figure out why codesigning was failing -- I had the pf block set up correctly, my keychains were unlocked, and then, eventually, it occurred to me, hey, maybe an IP address changed, so I disabled IPv6 except for link local, and then amazingly, it went back to working. I filed FB13706261 over a year ago. This is ridiculous.

This has happened a few times, including out in the field; it's happened on macOS 14 and 15 I think. "This" is: our app runs, activates the extension, it has to get user approval, and... the system dialogue window never appears. The extension stays waiting for user approval. I've got sysdiagnose from one of the systems, and I see the system log about it going into the user approval needed state, and... nothing else. It's there in Settings, and can be approved then. Has anyone run into this? Ever?

On one test machine, our extension wouldn't load, because [NETransparentProxyManager loadAllFromPreferencesWithCompletionHandler] can't find a manager, saying Skipping configuration appname because it is of the wrong type. This is the first time I've seen this behaviour. (The containing app tries to find a configuration, if it can't find it it creates one, then modifies whatever it found or created, then stores it. I don't have the right logging yet for that, so I can't see the error messages. [NSLog instead of os_log_error.])

Clearly not percentage, but the units don't seem to be specified... The real problem we have right now is that, with macOS 15.5, our suite gets a huge amount of "energy impact" points, even though diving into it, it doesn't seem to do that. The most telling example I have of that is: I ran each of our daemons from Terminal, unplugged my laptop, closed the lid, and let it stay there for 8 or 9 hours. When I woke it back up, Activity Monitor claimed it had 2,000 units or so, but after opening all of the disclosure triangles, none of the processes (including the hand-started daemons) used anything close to that. Also, the battery had almost no drain on it. We're getting complaints about this, so I'm trying to figure out what, exactly is going on, but I never looked at the power stuff internally so I don't know how to read the diagnostic files.

For login purposes, we may want to try automatically checking to see if an email address is set up in certain databases. It looks like the preferred way to do this is via ABAddressBook.shared().me(), then get the right key via in the properties? This, however, is treated as accessing the whole address book and brings up a confirmation dialogue. However, as I thought about it, that might not be the real way we'd want -- we'd want to go through Active Directory, perhaps? Am I making any sense, or just being incoherent? 😄

The stuff I've found by searching has confused me, so hopefully someone can help simplify it for me? I have an app (I use it for logging which books I've given away), and I could either add a bunch of things to the app, or I could have another app (possibly a CLI tool) to generate some reports I'd like.

It looks like, for some reason, our apps are using a bunch of power sometimes. sysdiagnose has this in the power log: Never mind. Including the output of sysdiagnose has "sensitive language," and it won't tell me what is sensitive, making this a waste of my time. ETA: Ok, I I can attach the file: power.log I've gone through the energy documentation, but it seems geared towards embedded, not macOS, so I'm not sure how I can figure this out more. The extra problem, of course, is that we have a network extension, two daemons, and a GUI app. 😄

I have a vague memory this might be related to some code to pretend to be case insensitive, but I can't find it now.

* [Error] Failed to stop recording session: Failed stoping ktrace session. (xcode-select version 2409) So why can't it stop the ktrace session? And how long has that typo been around? 😄 (Look, I've kept typos in log messages for years because it differentiated that message from other messages.)

My load average on a largely idle system is around 22, going up to 70 or so periodically; SSMenuAgent seems to be consuming lots of CPU (and, looking at spindump, it certainly seems busy), but... it's not happening on any other system whose screens I am observing. (Er, I know about load average limitations, the process is also consuming 70-98% CPU according to both top and Activity Monitor.) Since this machine (although idle) has our network extension, I'm trying to figure out if this is due to that, or of this is generally expected. Anyone?

I have this code: var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16((EV_ADD | EV_ENABLE)), fflags: 0, data: 0, udata: nil ) I looked at it and thought why do I have those extra parentheses? So I changed it to var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16(EV_ADD | EV_ENABLE), // changed line! fflags: 0, data: 0, udata: nil ) and then kevent gave me EBADF. Does this make sense to anyone?
