This only works for awhile. I have same issue. DVD will work for awhile. If DVD goes unused for awhile, Mac "loses" it. Putting in a new DVD doesn't mount, unplug/replug doesn't do anything, using different USB doesn't do anything. Restart Mac, DVD comes back. Restarting is not a solution, its a bandaid and I expect more from Apple and the $3k iMac I just bought. BTW, I didn't buy the external Apple Superdrive because of all the bad reviews.

What do you mean it is not connecting? When you plug it in it will not show anywhere except in Disk Utility. Then when you put a disc in it that will show in Finder and on the desktop, if you have that option checked in the Finder preferences, and in Disk Utility just under the drive name in the left hand column.

I have a LG Slim Portable DVD Writer that I purchased back in 2014. I also have a MacBook Pro (Retina, 15-inch, Late 2013). When I initially used the DVD Writer, it worked perfectly fine. Now, my macbook isn't reading the DVD Writer; thus, I can't play any cds/dvds. Can you please let me know why it stopped all of a sudden? Is it incompatible now? I updated the latest Mac OS Sierra 10.12.6 (16G29). My email is mr.n...@gmail.com.

Finally out of frustration I tried a different plug which has a double usb (plugged both into imac) and then the normal plug that goes into the LG portable DVD writer and VOILA - worked like a charm :-) ... same was true of my Transcend hard drive!!!

So others can match up their symptoms, here's my story. I got one drive from LG and it didn't work in either my MacBook Air (mid-2011) or iMac (Early 2008) -- both running OS X 10.11.2 El Capitan. Got a replacement drive from LG and it didn't work either (until I restarted my computer with the drive attached)

Hi, I bought the LGs slim portable DVD writer know that I bought a product that is compatible with mac (says so on the box). I opend up the box and there was no installation disc for apple or installation instructions. Ive tried various ways to resolve this issue, ive tried patchburn but theres no version for my specific mac version. Does anybody know how to resolve this issue for me?.

I purchased the LG Slim Portable GP60 today and discovered that it works fine with my iMac running 10.6.8 but when I plugged it into my MBP running 10.8.4 it gives me an initialization error "A valid DVD drive could not be found." [-70012]. Oddly, I put a disk in the drive and it shows up on the desktop but will not play. Have you heard of this issue and do you know of any solutions?

It should be plug and play. I have a 3rd party external burner connected to my iMac. It burns data disks, with iDVD it can burn DVDs compatible with DVD players, and music CDs. I've never installed a driver for it.

Could you expand on your comment about the article you found? What article where? I've got an LG slim portable GP50 and have nothing but problems playing dvds on my mac air. Occasionally a movie will play but more often than not, it won't work.

I'm not sure what your issue is but here is the info I used to get my GP50 to work properly. I modified the DVDPlayback.framework file. You might try another media player first before modifying the file.

I had exact same issue, and not just with external DVD player, also with hard drives I was using to try and transfer backups of previous data...

Hope this helps!

I to was having this same issue. After using my drive to burn a dvd only once, it quit working as if my MacBook Pro would not detect it no matter what I tried. So, after reading this thread I switched out the usb cable that came with my drive for another one that I had lying around and now my drive works perfectly every time. I am wondering if LG might have had a bad batch of usb cables that all ended up in these types of drives.

I walked into the same problem. I have a LG Slim Portable DVD writer GP30NW20. I used a USB-cable to plug in. Didn't work. Then used the USB cable (USB 2.0) that had been supplied with the device. It's a somewhat thicker cable with an extra USB connector. Now it worked.

Slim reader/writer (SRW) locks enable the threads of a single process to access shared resources; they are optimized for speed and occupy very little memory. Slim reader-writer locks cannot be shared across processes.

Reader threads read data from a shared resource whereas writer threads write data to a shared resource. When multiple threads are reading and writing using a shared resource, exclusive locks such as a critical section or mutex can become a bottleneck if the reader threads run continuously but write operations are rare.

Shared mode, which grants shared read-only access to multiple reader threads, which enables them to read data from the shared resource concurrently. If read operations exceed write operations, this concurrency increases performance and throughput compared to critical sections.

Exclusive mode, which grants read/write access to one writer thread at a time. When the lock has been acquired in exclusive mode, no other thread can access the shared resource until the writer releases the lock.

Exclusive mode SRW locks cannot be acquired recursively. If a thread tries to acquire a lock that it already holds, that attempt will fail (for TryAcquireSRWLockExclusive) or deadlock (for AcquireSRWLockExclusive)

A single SRW lock can be acquired in either mode; reader threads can acquire it in shared mode whereas writer threads can acquire it in exclusive mode. There is no guarantee about the order in which threads that request ownership will be granted ownership; SRW locks are neither fair nor FIFO.

An SRW lock is the size of a pointer. The advantage is that it is fast to update the lock state. The disadvantage is that very little state information can be stored, so SRW locks do not detect incorrect recursive use in shared mode. In addition, a thread that owns an SRW lock in shared mode cannot upgrade its ownership of the lock to exclusive mode.

The caller must allocate an SRWLOCK structure and initialize it by either calling InitializeSRWLock (to initialize the structure dynamically) or assign the constant SRWLOCK_INIT to the structure variable (to initialize the structure statically).

If you want something "portable" in the sense of conforming to some standard... If you are using POSIX threads there is pthread_rwlock_init() and friends. These are of course not typically used on Windows but rather Unix-type OSes.

But if you mean "portable" in the sense of "portable to multiple versions of Windows..." There are some undocumented calls in ntdll which implement RW locks. RtlAcquireResourceShared() and RtlAcquireResourceExclusive().

If you don't want to use pthreads and you don't want to link to sketchy undocumented functionality... You can look up a rwlock implementation and implement it yourself in terms of other operations... Say InterlockedCompareExchange(), or perhaps higher level primitives such as semaphores and events.

You can certainly roll your own using the same ideas as slim rwlock (at least what I imagine they did, since this is fairly straightforward). I outlined the approach in some detail in this other question.

For your case, you can mostly ignore the "fair" aspect, but the implementation is essentially the same. In particular, if you are willing to let an indefinite stream of readers block writers, you always let readers in when the lock already has readers in it (i.e., state (2) and (3) more or less collapse together).

In your case, for the cross platform angle, you would need to implement the blocking with either windows events or pthread condvars - but the details are similar in either case. Or, if you really want to avoid blocking at all, your only choice is spinning (ideally using the pause instruction to be nice to the CPU), which makes things even easier by removing the whole fallback to blocking code.

I fell into my writing career as a nave yet enthusiastic blogger in 2005. After blogging for a couple of years, I realized that I loved writing. I found blog readers, and eventually my publisher Penguin Portfolio approached me about doing my first book, Escape from Cubicle Nation.

My area of expertise as a writer is building a relevant, sticky, and significant body of work through writing and publishing online. I also talk a lot about the connection between online and mainstream publishing, including going from blog to book.

I work best when I have a clean desk, a fresh cup of hot coffee and some good music playing. So I get those things in place, crack my knuckles over my keyboard (it makes me feel like Bruce Lee) and get started writing.

Dan and Seth have a way of making complex business ideas simple and accessible. Nancy is meticulous in her research and visual organization of ideas. David and Anne make me weep with laughter. Gabriel and Isabel light up my imagination with their magical realism. Bren and Martha blend great, accessible storytelling with humor, academic research, and useful self help tools.
