Arduino and Mac OSX

Recently, Spotlight running Mac OS X El Capitan stopped working. I searched the web and found that it can be relaunched in Terminal with:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

I believe Arduino software, owing its save system, shuts "indexing" off.

I am a novice Arduino user and Unix user. I am looking for someone who knows these programs and a patch to fix this problem.

I believe Arduino software, owing its save system, shuts "indexing" off.

I don't think so. At least, I've been running Arduino since about v0015 and haven't noticed spotlight turning off.
(OTOH, I'm still running Mavericks.) I'm not sure what you mean by "owing its save system", and can't think of a reason that Arduino would want to turn off indexing. (and, just checked, spotlight finds recent changes to a .ino file just fine...)

I also had the same issue a few weeks ago, I just deleted the index file and started reindexing. After this procedure Spotlight worked normally. Spotlight had this issue only when I switched to El Capitan. I also believe it could be the Arduino Software.

Huh? Care to elaborate what this jibberish means?

I am running El Capitan on multiple Macs, all with various verison of the Arduino software, and have not experienced this issue.

Spotlight continues to work fine.
