I've even left for a total of 24 hours and nothing.

I left overnight (8 hours) and still stuck in the preparation of backup mode. Since this problem started, the Time Machine backup 'preparedness Back Up Now' never of leaves. I'm religious about backing up (about every 2-3 weeks) and my normal backups take about 30 minutes (usually leave it all night in stopping in bed). I did not this again, because my Time Machine hangs and won't give me a recent backup. The next step on the list that I saw on the forum is to reinstall OS X.

The amazing thing is that the beach ball turns constantly and at the same time my activity monitor says I have 90% of free CPU while my reel becomes crazy. The machine will be restart as suddenly about once a day for a reason any. Always turn the ball and beach closing my apps suddenly by itself. Then, I started in HD recovery using the command-R and repair the hard disk and permissions using first aid option in disk utility. Then I booted the computer in Mode safe and also reset the SMC. Since the upgrade, I reset memory PRAM/NVRAM, recommended in this forum. Seems that upgrading RAM reduces the time of 'spin'. It runs the same as before, but the delay/spin isn't as long as it was before. Unfortunately, this did not help to remove the rotation beach ball.

I feel upgrade my RAM anyway (we stock 4 GB), so I buy new RAM and upgraded to 16 GB. I ran a scan of material and everything checked, including the RAM. This would help the lines/beeps etc, but the beach ball began to spin all the time.

After searching for the reason for this, I found that it was probably a RAM problem and saw messages recommending to turn on and remove two cards of memory RAM. The computer would then closed and when I started it again, I would get three consecutive beeps.

The problems began with suddenly a series of cruise lines up and down my screen in vertical columns. I'm not sure it's related, so I don't want to blame the new version, but wanted to mention. After about 3-4 weeks after the upgrade to El Capitan, I started to have problems. The computer is still very well without any problems. I tried to implement everything that I know and I now return to the pros. MacBook Pro a mess (maybe after upgrading to El Capitan) When it's 4 GB or 6 GB, it works very well, even if a bit slow since I installed El Capitan, this is why I'm upgrading from memory. This machine is supposed to be expandable to 8 GB. Any combination of 6 GB, regardless of the RAM use what slot, also works fine. I already tried all of the various combinations of these 6 Rams (2 old 2 GB and 4 new 4 GB). They are 204-pin DDR3 SO-DIMM 1600 (PC3L 12800) Rams, which seems to be the correct type. I've tried 2 different sets of 4 GB RAM, a couple was second hand, the other Crucial nine pair. because when I try one of the new RAMs (4GB) with one of the old RAMs (2 GB), it works fine. I'm sure that's not on the Rams is not inserted properly or dusty slots etc. The Macbook I have is a mid-2009 and OSX El Capitan. I saw that others had the same question, but mine seems to be a little different. I am trying to improve my Macbook Pro 4 GB to 8 GB memory, however, when I start the laptop it emits 3 beeps, without loading the operating system and just keep it. The basic circuit is also very forgiving on the power supply voltages (5-15V), a 9 volt battery will work well.MacBook pro emits 3 beeps after upgrade memory If the battery is far away then you might want to put a filter cap on the power supply. The capacitor on pin 5 isn't necessary, but will prevent glitches for more precision applications. 1uF cap for R and C will give you a minimum frequency of 70 hertz, which isn't quite sub audio but close. You could even experiment and eliminate the 100 uF capacitor on the 1st circuit, if the speaker can take the DC then it will work OK. 555 ICs are not meant for high power, but they are cheap and available almost anywhere parts are sold. Use the power supply for the 1st circuit to turn it on/off, the third schematic shows a way of digitally turning the oscillator on/off, as well as a major power boost if the first circuit is too quiet, while the second circuit shows a more conservitive way of boosting power (you will need a power transistor and a possibly a heatsink). The pots maximum value sets the low frequency, you should be able to adjust it to whatever note you want. If you still want to built the classic astable you pointed out let me know.
