Left 4 Dead 2 Macos

[Leonides Suttle]

Leftairpod is dead. There is no sound coming out of it, I can only get sound out of the right one. Airpod battery status does not display on iPhone 8. I can see the status on the iMac. Says left has 0%, right has 100%. Case is fully charged.

You've tried some good steps already. If you haven't yet, be sure to try cleaning both the affected AirPod as well as the charging case. This will help to ensure that the AirPod makes proper contact for charging. The approved suggestions for cleaning can be found here: How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods

If you still have issues getting the AirPod to charge, we'd recommend following up with Apple Support directly to explore your available options in the region. This link can help start a support request: Get Support

Just a heads up for all admins who have 16" MBP in storage as a result of COVID-19. If you leave your machines in long-term storage and the battery drains completely you may never be able to boot or charge them again. There is an unconfirmed Apple bug that these models when discharged completely and left to sit, will not boot. I have one in my possession that is in this state. A user left it in their drawer during COVID and it sat there for months and when they tried to start it, nothing. Using 96-watt charger and plugged into different outlets and different chargers, and different ports. All you see is a battery icon that has a sliver of red, it then disappears and shows up when you press the power button. Did an SMC and an NVRAM reset and it did nothing. Let sit plugged in and charging for two days. I opened it up and reseated the battery and TB3 ports to no avail. The only thing you can do is send it back to Apple for replacement.

Could be totally unrelated but have you tried a DFU revive? I've had four of the 16" brick seemingly dead and need to be shipped back from remote staff only to be fired back up once a DFU applies. Full disclosure I also had one that totally ate it and had to be sent to Apple for repair. I've never had the icon on the screen you mention but thought I'd throw it out just in case.

Interesting post. This just happened to one of our 16-inch machines that came out of storage this past week. We set up a mail-in repair with Enterprise AppleCare. I just got the e-mail yesterday that the repair was completed and the machine was being shipped out. I should have it back tomorrow. Will be interested to review the repair summary and see what was done.

We have had this same issue with 15 of our 2019 16" MacBook Pros which sat on the shelf since February this year. I thought it was only us who had a faulty batch! We had to call Apple Support and get them replaced. The repair summary mentioned they reseated the RAM modules and wiped the OS.

We have this kind of issue with our Macs.

We let quite long (six months+) some 13' 2018 MacBook Pro stored and when we tried to power on them, they didn't.

It resulted for most of them a damaged battery, with no ability to power on again, or if so; when disconnecting the power supply, the Mac suddenly shuts down.

I think (for our case) this is not anormal, this is how these kind of batteries behave.

According to the Apple documentation:

-performance/

If you plan to store your device for longer than six months, charge it to 50% every six months.**

Okay, it doesn't tell your battery will be damaged, but Apple gives anyway recommendation to follow and this is probably not for nothing.

Sorry. Call me cynical, but if leaving a brand new $2000+ laptop in storage for more than six months is going to render the machine useless, then Apple needs to be upfront with their customers about that. At the start of the pandemic, we pulled used machines that had been in storage for years that had no problem powering them up and charging them. New laptops not starting up at all from a depleted battery is not normal.

I think I have just come across one of these in the wild. Wife had this 16" MBP at home since the start of COVID, new in box, still shrinkwrapped. Today she said "I'm testing Jamf Connect and haven't used it yet. Can you do me a favor and do an internet recovery up to Big Sur?" Sure thing, honey. I plug it in, battery's dead. I wait an hour. Press the button. Still getting the red battery charging indicator. OK, maybe it was really really dead, but this is odd for a new Mac.

It has been 10 hours charging and still gives me guff about the battery. It will respond to an SMC reset and attempt to go into DFU. If I hold down the special key combo for 10-15 seconds, there is a "huff" of air from the internal fans bursting up to 100% and then back off.

Update: the Apple logo briefly appeared on the 16" MBP while AC2 showed "Step 4/4: Installing System..." Then the screen went blank and nothing else happened. Apple Configurator 2 now shows the padlock / Apple Controller, as if the system is out of DFU and no longer available for reprogramming. I wonder if anyone else with a similar problem witnessed a similar sequence of events.

We've had similar issues on our 13" as well, only issue major differences are the users are using them up till the battery dies, then it never powers on again other then the trackpad continues to click but no other signs of life.

FYI, I am using an Anker 60W USB-C charger with an Anker USB-C cable, not the Apple 96W unit. It would appear that 60W is enough to charge this laptop, albeit a little slower, but certainly enough juice to keep it full under all but the most extreme circumstances.

@bradtchapman, I was able to get the same results with the dead one I have. It took trying off and on all day to actually get it to go into DFU mode. It kept showing up in Configurator 2 for about 1 second and then disappearing again. When I finally got it, I had to do a DFU restore twice to get it to take. I'm installing the OS in Internet Recovery as I type this. I was using the Apple 96W charger.

I found that I needed to have power into one port as well as a data port connected to my host computer. Because the battery was only 1%, if I did not have the power connected I could not get it into DFU mode. I was then able to "revive" the laptops and all are working!

We had similar issue before COVID with 13-inch 2017-year models (our 2018 year purchase and inventory). We have to plan the budget, and purchase only once a year, usually on the end of the year as one big order. Then taking from inventory whenever some are needed to be deployed. At the end, about 25-30 of those MBPs were not turning on. Sure, when we found it, the year warranty passed for a month or two, and Apple wanted us paying $200 for battery replacement + service fees. We had long fight explaining the situation that for us those devices were brand-new-in-plastic-never-opened. Finally, we've got those serviced for free, but it was a lot of frustration, escalations, waste time and pain

To back up Mark on this it was close to 80 systems between 2018 model 13 inch and 2019 model 16 inch. About a third got new logic boards, the rest maybe a DFU that we couldn't get to work. We have started to charge all systems that are sitting on the shelf more than a few months.

Left 4 Dead is a 2008 first-person shooter game developed by Valve South and published by Valve. It was originally released for Microsoft Windows and Xbox 360 in November 2008 and for Mac OS X in October 2010, and is the first title in the Left 4 Dead series. Set during the aftermath of a zombie outbreak on the East Coast of the United States, the game pits its four protagonists, dubbed the "Survivors", against hordes of the infected.

Left 4 Dead uses Valve's proprietary Source engine, with four game modes: a single-player mode in which allied characters are controlled by AI, a four-player co-op campaign mode, an eight-player online versus mode, and a four-player survival mode. In all modes, an artificial intelligence dubbed the "Director" controls level pacing and item placements in an attempt to create a dynamic experience and increase replay value.

Left 4 Dead was well received by the industry media upon its release, with praise for its replay value, focus on cooperative play, and cinematic feel, although some criticized its limited level selection and lack of narrative. Considered one of the greatest video games ever made, the game won several publication awards, as well as distinctions from the Academy of Interactive Arts & Sciences and British Academy of Film and Television Arts. As was done with Team Fortress 2, Valve supplemented the game with free downloadable content. The success of the game led to the development of the sequel Left 4 Dead 2, which was released in 2009. In 2012, all Left 4 Dead campaigns were ported over to Left 4 Dead 2, with cross-platform multiplayer support between Windows and Mac versions of the game.
