Bounty: 50

I am able to run the app in Debug mode in XCODE and simulator without any errors. But when I build for Release Mode the build fails with below 2 errors:

  1. ‘FirebaseCore/FirebaseCore.h’ file not found
  2. Could not build Objective-C module ‘Firebase’

I have been trying different solutions available on Stackoverflow and gitHub over last 10 days but know seems to be working, below are the details.

#StackBounty: #macos #google-chrome #macbook-pro #cpu-usage #osx-yosemite How to stop Chrome from using 100% CPU periodically

Bounty: 500

So when I open up the computer again after standby Chrome starts to use 100% CPU by itself without me doing anything. It last for about 10-20 seconds.

The problem is that my battery health is around 50% and because of high CPU usage for long periods of time the battery can’t handle it and the macbook goes back into sleep and I can’t bring it on unless I plug the power adapter even if it’s charged > 90%. This is really annoying and I only have this issue because of Chrome. Any other apps I can control the CPU usage so it’s not a problem.


ffs, someone please help, I can’t stand this anymore. This browser is destroying my life 🙁

In task manager it shows that while CPU is maximum network activity is also at max, so obviously it’s "calling home" and sending whatever. How can I block the network request, if I can’t block the CPU? I have little snitch but I don’t know what rule or what address I need to block.

PS: NOW after some update it started to do this every 2-3 hours, not just after standby, and it takes about 15% of the battery when battery is full, or it just makes the laptop go into sleep mode if battery is below 60%.

#StackBounty: #macos #ssh #openssh Set PATH when SSH into MacOS

Bounty: 50

My problem is

$ ssh localhost fswatch          
bash: fswatch: command not found

when without SSH command (i.e. fswatch) works fine.

I found that PATH in SSH session is default Mac’s

$ ssh localhost echo $PATH        

since without SSH

$ echo $PATH

I really do not remember how have I set up the PATH, but sure ~/.bashrc and ~/.bash_profile do not edit PATH variable. There is a config file /etc/paths:

$ cat /etc/paths         

Homebrew, npm, pip usually install programs to /usr/local/bin, so all installed programs are there and I can’t access them via ssh localhost command on my MacOS. There is no problem with Linux.

So my question is how to configure OpenSSH to use PATHs from /etc/paths and /etc/paths.d?

I also tried to hack:

$ ssh localhost sh -lc 'echo empty;echo $PATH'

$ ssh localhost bash -lc 'echo empty;echo $PATH'


first line is always empty, don’t you know why?

And my final workaround

$ ssh localhost bash -lc ':; 
    export PATH="$( cat /etc/paths /etc/paths.d/* | tr \\n : )"; 
    echo $PATH; 
    fswatch --version'
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Applications/VMware Fusion.app/Contents/Public

#StackBounty: #ios #swift #macos #coreml NLTagger: enumerating tags of multiple types in one pass

Bounty: 200

Using the NLTagger class, I’m wondering if anyone can recommend the most straightforward way to enumerate through the tagged tokens in a given text, but pulling out multiple tag types per token. For example, to enumerate the words in a given text, pulling out (lemma, lexical category) for each.

It seems that the enumerateTags() method and associated NLTag class have the limitation of only reporting one particular tag type per enumeration. So I can achieve what I want by making multiple passes over the text, e.g. pulling out the string ranges that match given criteria on the first pass and then matching things up on later passes. For example, I could lemmatise all of the nouns and verbs like this:

let tagger = NLTagger(tagSchemes: [.lemma, .nameTypeOrLexicalClass])
tagger.string = //some text
let keyWordCategories: [NLTag] = [.noun, .verb]
let options: NLTagger.Options = [.omitPunctuation, .omitWhitespace, .joinNames]

// In the first pass, we're going to record which ranges are of categories we're interested in
var keywordRanges = Set<Range<String.Index>>(minimumCapacity: 200)

// First pass: which are the nouns and verbs?
tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .nameTypeOrLexicalClass, options: options) { tag, tokenRange in
    if let tag = tag {
        if (keyWordCategories.contains(tag)) {
    return true

// Second pass: lemmatise, filtering on just the nouns and verbs
tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .lemma, options: options) { tag, tokenRange in
    if let tag = tag {
        if (keywordRanges.contains(tokenRange)) {
    return true

This mechanism achieves the desired functionality, but strikes me as a somewhat clumsy and potentially inefficient way to have to go about things. I would have expected to be able to enumerate (lemma, lexical category) in a single pass. I’m assuming that the NLTagger instance caches things behind the scenes so that it’s not as terrible as it looks in terms of efficiency. But it’s still far from ideal in terms of simplicity of the code. Can anyone more familiar with this API advise on whether this is really the intended pattern?

#StackBounty: #macos #bash #shell #zsh Shell set to bash but running zsh

Bounty: 50

I tried out zsh, but decided to revert to bash because it’s what I’m used to. I’ve set my "Login shell" back to /bin/bash in System Preferences > Users & Groups > Advanced options and have run chsh -s /bin/bash. When I run echo $SHELL I get the expected "/bin/bash" output. However, the top of my terminal windows says " – ZSH – bash" and when I force an error, like searching for something that doesn’t exist, the message seems to indicate that it’s still running zsh:
zsh: no matches found: *test

I’ve tried to force it to be bash in every way I know how. What am I not thinking of? Any/all suggestions appreciated.

#StackBounty: #zsh #macos #autocorrection Why does Zsh correct ssh User@ip1 to User@ip2, and how to stop it?

Bounty: 50

On Mac OS X 10.9 and zsh version 5.0.2 (x86_64-apple-darwin13.0) the ssh user@ command traps a correct to ssh User@ [nyae].

I don’t want to disable zsh correction on the ssh command completely.

How figure out why zsh wants to make this correct, and prevent it from occurring?


  • ssh User@ also zsh correct to User@
  • ssh does not trap the zsh correct to ssh
  • ssh User@ does not zsh correct to User@
  • there is a .zsh_history file of 2013 while zsh is configured for a maximum history of 2000 commands
  • removing all occurences of ssh User@ from .zsh_history doesn’t improve
  • both and list as host on tab completion
  • minimal .zshrc where the issue occurs contains only: setopt correctall

I tried reinstalling it multiple times and also followed instructions for complete removal. So far without any success.

In the log I see the following suspicious message:

I have not idea what else I could try. I guess the helper tool should be code signed. I have no idea why it isn’t or how I can change it. Also I found nothing about this online.

#StackBounty: #macos #iwork-pages Right Ident on Right Justified text changes bottom border in Apple Pages

I’m trying to add spacing on right justified text without changing the bottom border using the most recent version of Apple Pages.

If you change the left ident it just moves the text in, but if you change the right ident, it moves the border in as well.

Is there any way to achieve having the border go all the way across with a right ident and text justified to the right?

#StackBounty: #xcode #macos #nstableview #appkit NSTableView selected row flickering while scrolling with arrow keys

Bounty: 200

I have a view based NSTableView and can’t figure out how to work around a visual glitch where the currently selected row flickers while scrolling up or down with the arrow keys.

The selected row should appear ‘glued’ to either the top or bottom of the view, depending on scroll direction. The Finder shows this correct behavior in list view but a regular table view seems to not behave this way out of the box. I’m confused as to why that is and see no obvious way to circumvent it. Can anybody point me to possible causes / solutions?

Edit No. 1

A cell based NSTableView behaves in the desired way by default, so this is presumably a bug specific to the view based implementation. I don’t want to use a cell based table for unrelated reasons though.

Edit No. 2

I’ve tried making the table view’s parent view layer backed, as well as intercepting the up / down arrow keystrokes to do my own scrolling, but so far I haven’t been able to eliminate the flickering.

Edit No. 3

I’ve created a small sample project that reproduces the issue.
