NOW, though the product title DOES say that it comes preinstalled with EL CAPTAIN (or whatever), mine already came with the SIERRA update. It had Sierra Version 10.12.3 and in the app store, you can update it (FOR FREE) with the May 2017 recent Sierra 10.12.5 update! IF yours comes in with EL CAPTAIN, you can update it FOR FREE to the 2017 Sierra update - do not worry! Lol.
“Prior to the laser we fabricated all our components on the turret press or on manual machines. The operations required hours of cleanup. Punch-formed parts and louvers are reserved for our existing turret punches but the laser has taken on 90 percent of the workload with minimal cleanup. We’ve been able to reclaim that time and move our manpower from the hand labor it took to make and clean parts to assembly work instead. As a result we’ve increased output, stepped up assembly time and cut fabrication time by weeks for some components.”
6d UI taking too long to load since 7.3.5 Since 7.3.5 my users interface is taking too long to load as soon as I log in, and most of the time this issue persists every time I reopen any of these tabs, like talents, collections, bags, mail.. I never ever had this problem before, I've tried deleting Cache, WTF folders and disabling all of my addons, but the issue continues.Thünda14 6d

Testing conducted by Apple in May 2017 using preproduction 1.8GHz dual-core Intel Core i5-based 13-inch MacBook Air systems with 8GB of RAM and 256GB SSD. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The iTunes movie playback test measures battery life by playing back HD 1080p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network and signed in to an iCloud account, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See for more information.
Called them and left a message on a Thursday about a month ago.  I also emailed the same day using their website form, indicating the specific issues I was having (model, OS, RAM, etc.).  The next day I got a return call from their admin saying only that someone would come to my house and it would cost $140 ($150?) for an hour.  Told her I had emailed with the specifics, and I asked to speak with a technical person for a few minutes first, to get their view on my issues, whether they could solve it, and if so, how long it might take.  She assured me I would be contacted.  I received no reply to my email and no call.
My answer for reversing Safari's new rule for blocking autoplaying came to me in a slightly roundabout way. After searching for "videos in safari aren't autoplaying," I only got results about disabling videos from autoplaying. But clicking on the "Stop autoplay videos" result brought me to a page where I saw a link that said "Customize browsing settings per website," which revealed how to change the autoplay settings for specific websites.
