Sleep is saving contents to RAM.

Hibernate is saving contents to the disk.

Hibernate 0 disables hibernation.

Standby is how long it takes before going from sleep to hibernate. Seems redundant to change if hibernate is disabled.
False, it is not redundant since there is a difference between Sleep and Hibernate mode 0. The first puts the computer in a low powered stated to allow the system to quickly resume working, multiple components including CPU, SSD and Ram are put in low power mode and this is where battery consumption is increased when you use an NVME drive since it does not have the ability to put NVME drives in their lowest power state. The second powers off all components of the mac except the RAM where the contents are stored, as such the computer can stay in this state for longer periods of time. If you leave standby on then there is a period of time for which the mac is not completely powered off and users will experience significant battery drain until standbydelayhigh/standbydelaylow minutes have elapsed. This is why it is recommended to disable standby as well.

You may not consider mode 0 to be a form of hibernation, even though it is, but the point still stands that there is a difference between sleep and mode 0. The default hibernate mode of macs is actually mode 3 which is a combination of 0 and 25, essentially by disabling standby and not letting your battery die when the lid is closed you would effectively be achieving the same thing as mode 0 and standby disabled, only if your battery dies you'd have the wake up problem that 2013/2014 macs experience because mode 3 will attempt to restore the contents from the disk.

Everything I said is correct but you now seem to understand the difference between sleep and hibernate as you just described them like I did before you.

I was initially mentioning that it seems redundant to change both standby and hibernate mode to prevent hibernation which you seem to agree. I never mentioned changing sleep mode and I already explained the difference between hibernate. So confused with your response LOL.

You are confused because you still didn't grasp the process of the different power states for a Mac. If you change the standby mode, closing the lid will force the mac into hibernate mode 0 bypassing the sleep state, there is a difference with the two states hence it isn't redundant to change both modes, hibernate mode 0 is not the same as standby/sleep. You can test this yourself if you want using the following:

1. Set hibernate mode = 25 and standby mode = 0 then in terminal write sudo pmset sleepnow
2. Set hibernate mode = 25 and standby mode = 1 then in terminal write sudo pmset sleepnow

The first scenario will crash the mac because it has gone directly into hibernate, the second scenario will not crash your mac because standby is enabled and the system has not directly gone into hibernate mode. The same applies to mode 0 with no crashing in either case. The battery drain is caused by the mode between awake and hibernate which is resolved with standby=0

I totally grasp it as I have explained LOL I’m saying that to avoid hibernation issues with NVME SSDs you can simply disable hibernate by using hibernate 0 and shouldn’t have to change standby settings (or vice versa) since hibernation is now disabled. I understand that both settings aren’t redundant in general but we are talking about avoiding hibernation with Macs using NVME SSDs that don’t have the DXE driver.

Hibernation mode 25 should never be used if trying to avoid issues with NVME SSDs because it end up saying the contents of memory to the disk so I’m not sure why you even mention it?

i experimented with few of the various power modes.. lots of people mistake "standby" for "sleep".. standby is another form of hibernation so is autopoweroff.. all 3 modes work independently of each other, I initially thought turning hibernate mode to 0 would remove all hibernate functions.. false.. if you read the pmset manual it actually explains it.

The “standby” value in pmset is not a form of hibernation but is to say if the Mac will go into a hibernation mode after the the “standbydelay”. “standby 1” is on and 0 is off. With “standby 0” the “standbydelay” and “hibernate” mode no longer matter and the Mac just sleeps.

“autopoweroff” was introduced by Apple to meet European Energy Standards requirements but affects Macs worldwide. When enabled a Mac in sleep state will move the contents of memory from the RAM to the drive (hibernate 25) after 4 hours if plugged into power. It’s good you mention this because it will still occur even with “standby 0”.
 
With “standby 0” the “standbydelay” and “hibernate” mode no longer matter and the Mac just sleeps.
It is necessary to note here that with standby 0, the Mac will bypass the normal sleep that it would otherwise enter if standby was 1, and will directly execute the hibernatemode. Thus if hibernatemode is 0 or 3, it will enter normal sleep until the autopoweroffdelay is reached (if plugged in) and then hibernate. If hibernatemode is 25, it will enter hibernation.

Therefore, we have concluded that in order to entirely disable hibernation, ALL the three modes should be set to 0.

sudo pmset -a hibernatemode 0 standby 0 autopoweroff 0

hi all,
i have macbook pro retina 2015,
i have a problem with WINDOWS when closing the lid the computer never comes back
is there a fix for that ?

The heatsink is really nothing more than a thin strip of aluminum that is attached to the SSD using heatsink adhesive. I doubt it would make much of a difference since the interior of the Pro is pretty cramped without great airflow over the SSD. Depending on the thickness of the SSD, adding a heatsink may prevent the bottom casing from fully closing.
thank for your answer man!
I bought the ADATA sx8200 PRO, and it came with a heatsink (as shown in the picture), so just for me to be sure.. You guys recommend that I should NOT put the heatsink on the SSD after installation?
Thanks!

There may not be any harm in applying the heatsink if it doesn't interfere with closing the bottom casing and doesn't trap heat against the SSD.
 
Hello Everybody,
Yesterday I put a Corsair MP510 960GB in a MacBook Pro (Retina, 13-inch, Late 2013). Using the USB bootstick I formated the drive to HFS+ with the Disk Utilities. I installed High Sierra via USB bootstick with the --converttoapfs NO option and restored from a time machine backup.
Boot ROM Version is 149.0.0.0.0 as I had installed the current version of Mojave on the original SSD beforehand.

As I was curious to see how much battery the MP510 would drain overnight I did not change anything on hibernatemode, standby or autopoweroff settings, and left the machine with 100% battery yesterday evening (just closed the lid).

8h later (this morning) I opened the lid, OSX was there instantaneous and the battery still showed 100%.

I had expected more battery drain. Is this due to the battery not being exactly measured at 100%?

On all my Macs hibernate 0 disables hibernate and the standby value has no effect which is the expected behavior. You’re saying with NVME SSDs the behavior is different and that a Mac will still hibernate with hibernate 0 unless standby is also disabled?
 
You can set a low standbydelay in seconds and test it yourself :)

I am convinced that when on battery power the standby hibernates the Mac automatically after reaching sleep for ”standbydelay” (low or high depending on the battery’s current charge) seconds. This is regardless of ”hibernatemode”. On the contrary, when plugged in, ”autopoweroff” is what kicks in for a laptop after sleeping for the default 8h.
 
guys help! I am having trouble installing the new ssd because it covers the screw hole by a few millimeters (see picture), and i cannot get the screw to get in!

what can be done about this?

Thanks!

Which adapter are you using?

The adapter is completely inserted?

Some people used a tool to enlarge the SSD's screw notch area.

I bought this one: http://eshop.sintech.cn/ngff-m2-pcie-ssd-card-as-2013-2014-2015-macbook-ssd-p-1143.html

yes sir, completely in, but the hole is still covered by a few mm D:

you mean to cut the SSD?

Is there no other way/method for me to get it in without cutting the ssd?

I have the same adapter with an Intel 600p and HP ex900. Both drives fit perfectly.

Your drive is the sx8200? Enlarging the notch is the only way to make it physically fit. Can you return the drive?
 
Hey guys:

So I'm about a month into my upgrade and I just want to give somewhat of a review of my experience so far.

Mac: 15" Mid-2014 MacBook Pro
NVMe drive: Adata XPG SX8200 Pro (512GB); Tried and failed with the Samsung EVO Plus (512GB)
Adapter(s): JSER 12+16pin; Sintech Black; Sintech Green [I own all 3 - they all work perfectly]

Pros and Cons are listed in order of significance to me

Pros:
1. Read: 1500MB/s, Write: 1300MB/s: About twice the speed of my stock 256GB Apple SSD
2. Significantly cheaper alternative to the proprietary SSDs that Apple sells
3. Doesn't void your AppleCare warranty, and the drive can be easily replaced with the stock SSD if you ever need to take your Mac into the Apple store

Cons:
1. The thickness of the adapter will not allow the bottom enclosure to snap into place completely [I really wish the adapters were a bit thinner so that the bottom would snap into place]
2. Machine will not receive firmware updates while using a non-Apple SSD (#3539)
3. Battery drain will be noticeable
4. 2013 and 2014 MBPs will experience sleep/wake issues unless you:
A) set standby, hibernate, and autopoweroff to 0, or
B) update the BootROM to that of a 2015 MBP

Conclusion:
I am very pleased with my experience so far and I do not regret the decision to upgrade. The 2013-2015 line of MacBook Pros are easily some of the greatest notebooks ever designed, far better than the poorly designed models that they sell now. My 2014 is still a capable machine and it doesn't show very many signs of aging. Yes, as a 5-year old computer it will eventually begin to show its age, but I anticipate at least 2 or 3 more years of use before I have to get a new computer. That said, the NVMe upgrade has added a bit more longevity to my machine while also increasing the storage capacity. Dollar for dollar, the NVMe upgrade is a far better alternative than buying an Apple, OWC, or Transcend SSD. Overall, I highly recommend the upgrade to users who are looking to squeeze a bit more life out of their aging 2013-2015. If you own a Mid-2015 MBP, this is a mandatory upgrade because those machines utilize the PCIe 3.0 protocol with 4 lanes (up to 3000MB/s Read and Write).

My 2015 13 inch Macbook Pro is still running amazing but I also need to run Linux and Windows for college and a 256gb SSD is simply not enough. After reading a little bit on the forum I'm thinking on buying the Sintech adapter (the long one - http://eshop.sintech.cn/ngff-m2-pcie-ssd-card-as-2013-2014-2015-macbook-ssd-p-1229.html) and a Crucial P1 1TB.

What's the difference between the adapters, the long and the short one? And which one should I really buy?

Also, I need a 1TB SSD and I don't know if the Crucial P1 is the fastest/stable one out there so I really would like to hear your opinions. The Samsung ones seem to run a little bit too hot and consume too much power, and I've heard good things about the P1. But since it's a small investment I'd like to make an informed buy.

Thanks!

Have you turn on the macbook to test? To my experience you haven't push the ssd in completely
Try to push it in, be gentle
 
Guys, I had some questions about replacing a failed SSD in my early 2015 13" MBP that got lost upthread.

1. I'm 90% sure the logic board is OK, and I was running Mojave before the drive died. If the logic board works, then, after swapping out the failed drive, will I need to do anything other than connect my external USB SSD (currently running Mojave) to format the new NVMe, download the Mac OS installer, and then install Mojave?

2. Suppose the logic board is slowly failing but works well enough for me install OS 10.14.3 on the new NVME. If I replace the logic board, will I have to temporarily install an Apple branded SSD on the new board to update the its boot ROM's even if the new SSD is now a properly formatted boot drive running Mojave?

3. Is there any consensus on whether the larger Sintech adapter will fit in the bottom case of a 13" A1502 MBP along with a double sided SSD? Or is the short adapter the way to go (some videos claim the smaller one caused occasional kernel panics because it didn't stay fixed in place all the time).

I'll try to answer your questions.

1) The process as described should be fine.

2) Yes, you need an Apple SSD to install a bootrom update.

3) I recommend the small black Sintech adapter. I recall seeing a post from a member who had to cut the long black adapter to fit everything in the MacBook.

I managed to insert the tiny screw! I had to bend the SSD just a little bit to get the screw to tight in the hole and it managed to fit, and now it works! thanks guys
[doublepost=1552882841][/doublepost]So i managed to upgrade my Macbook Pro early 2015!!!! :D :D I went from having 128GB storage to 1TB! :D
for noobs such as myself, I used the following parts

this is the adapter that I used: http://eshop.sintech.cn/ngff-m2-pcie-ssd-card-as-2013-2014-2015-macbook-ssd-p-1143.html

this is the nvme ssd that I installed: https://www.amazon.com/SX8200-Pro-G...8200&qid=1552881589&s=gateway&sr=8-1-fkmrnull

other stuff needed: a 16GB+ usb to create a bootable usb drive with MacOS High Sierra or Mojave, to make a fresh install of the MacOS on the NVMe SSD. (youtube link below will explain how to create a bootable usb)
An external harddrive to backup files from the apple ssd to then migrate files to the new NVMe SSD (not really needed; there are other ways to do this)

and finally, I used this video for guidance throughout the whole process of installing the NVMe ssd:

I hope this summary helps!

Sorry guys, but so: what is the best price quality solution?
Which adapter closes the macbook well?
Which ssd warms up less? need the sink?
Thank you, but I'm going crazy ...
wouldn't it be useful to make a summary on the front page?
:(o_O:) thank U :p
