Macbook Pro 13" M2 & Potential NAND Issue

 I'm noticing some videos of the recently released Macbook Pro 13" M2 throttling SSD reads and writes.

I've also seen some posts on MacRumors.com describing the issue.

It appears that Apple may have only included one NAND for the 256 GB version of the MBP 13" M2, while the M1 variant of the same notebook has two NANDs.  Apple apparently was cutting costs with the M2 MBP13, to the point that the M1 MBP13 certainly outperforms it as far as SSD reads/writes are concerned.

This might not only affect MBP 13" M2s, but also MBA M2s.  We'll soon see if the community discovers that the MBA M2 is also affected by this issue.

See this MacRumors post for more information.

Purchased Applecare+ for the Macbook Air

 After seeing a month+ of many folks sharing that they've damaged their Macbooks' screens (either by dropping or neglecting to remember that the notebook is fragile), I decided to purchase Applecare+.

The thing about insurance is that you might not need to use it.  I wanted to have it in case I ever need it.

I think I use my Mac Mini more than I do my MBA, but every time I handle the Macbook, there's this nagging feeling that I'm going to drop it.  Maybe it's that slick feeling case.  Or maybe it's the fact that it feels ultra-light and thin..  The top case is very thin, in fact, to the point that it doesn't take much to damage the screen (evidenced by the high amount of posters at the MacRumors forums and sub-Reddits, sharing the damage they caused).

One thing that I noticed is that when purchasing Applecare+, the owner is given the option of subscribing annually ($99/year) or paying a lump sum of $199 for three years of coverage.  I'm not sure which would've been best for me, but opted for the 3-year plan since I'll have the MBA a while (longer than 3 years, more than likely).  

It just makes sense, to me, to buy the coverage (mainly for the accidental) and not worry so much about display damage.  Note that I'm only interested in entertaining my use case...I've no need to explore any scenarios outside of my own usage patterns.

And, no, I didn't purchase Applecare+ for my Mac Mini M1.  It's not mobile and I have less worry of dropping it than my MBA.

Macbook Air M1 - Passive Cooling and Waterproofing Discussion

I saw a forum post where someone was wanting a waterproof Macbook Air.

I'm not sure why someone would want this.  The poster stated that it was for the sake of innovation, like adding needless features alone is considered to be innovative.

I explained that I've never spilled any liquids on any of the notebooks I've owned.  Sure, I'm speaking for myself, but self-restraint would prevent folks from accidentally spilling liquid on their notebooks.  I'd explained how I made sure I wasn't drinking over or even near my notebooks...that simple rule stopped me from ever having to worry about liquid damage repairs.  What of notebooks (in bags or backpacks) getting wet if caught in the rain?  Always check the weather before you leave an establishment, or don't take your notebook with you when/if you know it's raining.  If you need to go and you know it's going to rain, bring an umbrella or put your notebook inside a ziplock or plastic bag...it doesn't have to be airtight unless you're going underwater with it.

Some then made a quip of it being super simple to implement since the MBA was already sealed.

Wait.  What?

He thought that since the MBA had no fan, that the case was sealed (ie, no air gaps)

I told him that there is no way that the case is 100% sealed, even while the system is fanless.  I couldn't back this up, as there are no pictures or articles stating that there are no ports/ducts in the case, but I followed my gut.

I looked under my MBA M1 2020 and saw that there's a long rectangular cut underneath the display (when the display is lifted up).  At first I thought that this was where the ports were - I thought it was one elongated port, but I was wrong.  I felt along the port when opening and closing the lid, but couldn't find anything that suggested a true duct.

I powered down the notebook (not hibernated/sleeping).  I then closed the notebook and flipped it upside down.  I took a straightened plastic-covered paper clip and poked along the elongated duct.  I found that there are indeed two ducts within that elongated cut.  I thought they were hinges because they're covered by soft rubber pieces, but they flex away when prodded.

I also found this article: How The MacBook Air Cools Itself 2022 - The Mini Blog

That article clarifies some things.  

While it doesn't mention the two ducts, it does depict them.  The article explains that there are passive cooling mechanics designed into the system.  One passive cooler is the aluminum bottom plate.  It dissipates heat.  The system also has copper heat pipes, which are depicted within the article.  The article also explains that the CPU portion of the SoC (System on Chip) has what's called a cold plate over it, which helps dissipate heat.  

The below picture is an edit of what was depicted in the article.  The red circles indicate where the two cooling ducts are.  The copper heat pipes are circled in yellow.

What does this have to do with waterproofing a MBA?  Everything.  The MBA does not have fans and heat sinks on the hot bits to mitigate heat, as does the Macbook Pro and other non-Mac notebooks.  the MBA relies upon passive cooling.  A sealed case will cause issues with a system that uses passive cooling as the aluminum bottom alone won't wick the heat way.  What heat that is not dissipated by the aluminum bottom will not be able to leave the system, which is why the current MBA has the heat pipes and "exhaust" ports (the heat pipes absorb the heat and the pipes are pointed toward the ducts as another dissipation method).

The MBA as it currently stands, is nowhere near being waterproof-capable, as you'd have to redesign the whole passive cooling system to account for the fact that the system needs to be air-tight to prevent liquid damage.

I explained to the forum poster that the ports are in place and that I've verified that they are ducts (showed him the pictures in the article and explained to him that I checked the ducts and they are indeed ducts).  He hasn't said a word in reply.

Now, with all that being said, his question was in regards to the new MBA (2022 M2).  Since the new MBA isn't yet released to the public, all I had to rely upon is the outgoing MBA (2020 M1).  

Note that I saw the bottom of the new 2022 M2 (internet picture) and saw that it has the same telltale elongated cutout on the bottom of the case, so I'm betting that the new MBA has the same exact ducting, since that system also uses passive cooling.

Macbook Air M1 & Multiple External Displays

 I saw several folks on Reddit complaining that the new M2 Macbook Air only supports one external monitor.  Technical specifications state that one 6K display is supported but I saw several posts over the past 30 days stating folks have been using multiple external displays with the M1 Mac Minis, which uses the exact same SoC as the M1 Macbook Air.

I decided to check with my Mac Mini M1to see what it would handle and if it could see more than one external monitor.

My Mac Mini is currently connected to an iMac 27" Late 2009 using a Thunderbolt-to-miniDisplayPort cable.  I switch between it and the iMac using Target Display Mode, which I posted about a few weeks ago.  My gaming PC uses a Samsung 34" UltraWQHD screen.  I disconnected it from my gaming PC and connected the display to the Mac Mini using and HDMI-to-HDMI cable, connecting it to the Mini's HDMI port.  The result is that the Mini is able to use both screens without issue, with both rendering in  1440p.

I then attempted to use the same two displays with my MBA M1.  Since the MBA M1 only has the two TB ports on the left side of the system, I had to use my Anker hub, which has an HDMI port.  I found that the MBA M1 can only use one of the two 1440p displays at a time, not both at the same time.  I did not alter the resolution.  NOTE - since the MBA only allows the usage of one external display, using a hub isn't necessary; you can use the aforementioned Thunderbolt-to-miniDisplayPort cable, which will give you the option of 1440p with the 27" iMac.

I think that two 4k monitors is a too much for the bandwidth of the MBA M1 and I've seen articles mentioning that two 4K displays was too much.  I need to test to determine if it'll detect both displays if one is not 4K or if I have to lower the resolution on both for them to be detected.

There are solutions that will allow the usage of multiple displays with the MBA M1, but you've to install DisplayLink.  I haven't tried that yet.

To be honest, the 34" as an external (or second) display is extremely large...it's like having two screens when in 1440p.  That's actually quite enough space for me, but I'll make it a project of trying to get the two 1440p displays to work with the MBA M1.

Upcoming M2-powered Macbook Air & "Refreshed" M2-powered 13" Macbook Pro

 So, I saw the specs of the new and upcoming M2 Macbook Air.

The technical specifications for the M2 Macbook Air are here.

The technical specifications for the M2 Macbook 13" Pro are here.

Immediately noticeable is the fact that the M2 MBP is using the same chassis as the previous M1 Air, while also using the M2 chipset.  They almost certainly just shoehorned the M2 into the existing M1 Air chassis, as the case layout and specs are extremely similar.

Basically, the M2 MBA gets a proper refresh while the M2 MBP does not.

The major differences are:

The MBA has a 13.6" display while the MBP's display is 13.3".  Both systems' displays are LED-backlit with IPS technology.  Both had the same nit capacity.

The M2 MBA base machine will have the 8-core CPU with 4 performance and 4 efficiency cores, and 8-core GPU.  The M2 MBP base will have the 8-core CPU with 4/4 performance/efficiency cores and a 10-core GPU.

The M2 MBA option would be the 8-core 4/4 core with 10-core GPU.  There's no other option for the M2 MBP.

So, the base M2 MBP starts with the better hardware, and the M2 MBA can be optioned to use the base MBP chipset.

Battery comparison:  The MBA battery is rated for 18 hours of Apple TV playback, 15 hours of wireless web, has a 52.6-watt-hour LiPo battery and includes a 30W power adapter.  The MBP battery is rated for 20 hours of Apple TV music playback, 17 hours of wireless web viewing, and has a 58.2-watt-hour LiPo battery.

Both have the exact same RAM capacity and offerings.

Both have the exact same SSD capacity and offerings.

That doesn't seem all that bad, but as you further compare, you'll see that the M2 MBA now has a 1080P front-facing camera while the M2 MPB has the same 720P camera as the outgoing M1 MBA and M1 13" MBP.

The MBA now has a Mag-Safe charging port with two Thunderbolt 3 ports.  The MBP has the same layout as the exiting M1 MBP 13" - two Thunderbolt 3 ports.  Note that the MBP will lose a TB port when using a charger, since it doesn't have a dedicated charing port.  The TB and USB bandwidth capabilities are the same for both systems.

The MBA uses a non-Touch Bar keyboard.  The MBP uses the Touch Bar keyboard, otherwise both keyboards are the same, as well as the touch pads.

The MBA uses a new four-speaker sound system. Both use the same three-mic array and 3.5mm headphone jack.

Both the MBA and MBP M2s officially support only one external 6K display.  I'm not sure what's unofficially supported.  I've heard that the M1 MBAs and MBPs can support two 4K displays.

Price-wise, the M2-powered MBA base model will now cost $1199, while the upgraded M2 MBA will cost $1499.  The M2 MBP base machine will cost $1299, while the upgraded model will cost $1499.

All of the above hints that the M2 MBP may be performing a swan song and may be exiting the market.  While it's not really overshadowed by the M2 MBA, (they share the same chip and the chips are exactly the same), they do not share the same shell.  The comparison is not really fair since the M2 MBA got a real refresh and the M2 MBP did not - the M2 MBP got a new chipset but is using the same chassis as the outgoing M1 MBP 13".

It's almost as if Apple had a surplus of M2 SoCs that they wanted to utilize for the sake of usage...they had spare M2s and spare 13" MBP chassis and used both surpluses to make "new" systems.

It's odd behavior, to be sure.

We'll see if I'm correct in my assessment.

Compared to the outgoing M1 MBA, the incoming M2 MBA is apparently 20% more powerful/efficient.

Are Macbooks Durable?

 Some guy on one of the Mac subreddit groups wanted to secure his Macbook in his car with a tether to deter theft.

I left a comment saying that his main concern should be the heat inside a car.

The storage spec for current Macbooks:

Storage temperature: −13° to 113° F (−25° to 45° C)

The next argument was that a trunk would suffice.  I argued against that, as a truck would be just as hot (it is not a sealed compartment and the heat from the cabin would, in almost all cars with trunks, radiate into the trunk.  The next argument was that the trunk didn't have windows.  A car can get hot even if the windows were covered, as the car is basically a metal enclosure sitting under direct sunlight.  The storage spec for the current MBAs is 113 F.  That temp can easily be attained in a car's trunk.

The next argument was that MBAs are durable.  

THEY ARE MOST CERTAINLY NOT.  A simple Reddit search shows the following - reddit.com: search results - macbook cracked screen - and most of those hits are very recent.  Many of the posts include pictures of the damage too, so yeah, that statement was quickly debunked.

Folks, don't believe everything you see on the internet.
