A mysterious wave of crashing Apple Mac Pro computers affected several film and TV editors in Los Angeles on Monday, and it was initially thought that video editing software Avid was to blame, according to Variety.
Indeed, the crashing Macs appeared to be localized in Los Angeles, and those reporting the crashes commonly run the Avid video editing software.
The incident caused editors to warn their colleagues to refrain from turning off their Mac computers running the Avid software, as they might not get the computers to turn back on. The industry appeared almost panicked.
Avid itself seemed to go to red-alert. The company told Variety that it was aware of the issue, and Avid CEO Jeff Rosica and its CTO Tim Claman even posted a video on Tuesday reassuring its customers that the company was working “around the clock” to fix the issue and that company engineers were scrambled to locations where Macs were affected, according to Variety.
However, in the end, it was a Google Chrome web browser update that was the offender, Variety later reported on Wednesday.
Google published a post in its Chrome support forum that the latest version of Chrome could affect some macOS systems.
In its post, a Chrome support manager stated that the issue would only occur if a Mac’s “System Integrity Protection” was disabled.
That’s not something most Mac users would do, but professional video editors may disable their Mac’s System Integrity Protection setting in order to connect external audio and video hardware that aren’t typically compatible with Mac computers.
Google told Business Insider it had no other comment to add on the incident beyond the company’s forum post, linked above.
