Are there potential security issues if I run MySql Server?

I am learning MySQL and PHP, and have followed the instructions to download and install MySQL server on OS X Lion.
As I am beginner I am not sure if by enabling this I am leaving my system somehow more exposed to potential attack (I have selected the option "Automatically start MySQL server on startup").
So my question is: am I putting my system at considerable more risk by having this service turned on? Should I disable it when I am not learning how to script PHP?
If so, are there any simple instructions for making my system more secure while MySQL server is running?
I use the built in OSX firewall and Little Snitch.

Any time you run server software you are putting your systems at a higher risk. MySQL is known to be very secure. Still, there are ways to improve the security. You can restrict connections so that only localhost can connect to your server. Make sure you don't have default accounts/passwords or the root account enabled. Make sure to follow the initial securing procedures.
In general, MySQL is very safe. There isn't anything to worry about.

Are there any security issues with Quicktime player on macbook

Are there any security issues with Quick Time Player on macbook pro? 2010 model running Yosemite recently upgraded. Thanks!

No.

I have an imac G5 with a power PC chip running os 10.5.8. and using safari 5.0.6. are there any security threats i should be aware of? s there a

are there any security concerns using my PPC imac g5 running OS 10.5.8 and using Safari 5.0.6?

You could use a browser that does not use Flash or Java, as a safety measure when visiting sites; the Safari browser has no support or recent updates. TenFourFox v 24 is fairly good, and uses later Mozilla code, is compatible with powerPC computer limitations. SeaMonkeyPPC has a similar code, but acts a little different; and there still is iCab, a good browser that will run free, but asks you get a $20. license.
The Safari browser can be used to set a different browser up as system default, so it won't launch and open attachments or web pages; it has a setting in its preferences where you choose another browser as default. As I have four or five browsers and one dedicated to gmail (launched as signed-in, through notifier) that is how I've used the default, otherwise mine are all in the Dock.
There is no new upgrade for Adobe Flash plugin player, etc; but the one in their site for vintage is still available at getflash player at Adobe. Most prompts online are to get you something else, even adware loads up from some not-so-clever efforts to get people to install junk. So go to the source. Someone wrote a patch that is supposed to allow a later version of Flash player to work in older 10.5.8 PPC Mac, but I have not tried it.
The thread of security is mostly based on the user and their caution to avoid odd free software and also avoid some sites that try to get people to load cleanmymac or genieo, or other adware malware voluntarily. Those are troublesome and hard to remove, and can waste processor cycles, slow the computer & mess it up. Mostly from a browser the adware issues arise. For those you see The Safe Mac and read up on the adware removal guide, among others linked on the page: http://www.thesafemac.com/arg/
So anyway, there is really nothing new on the face of it for obsolete OS X systems users.
Good luck & happy computing!

Are there any known issues running MAC OS X 10.8.5 on my IMAC and MAC OS X 10.6.8 on my MAC Server?

Are there any known issues running MAC OS X 10.8.5 on my IMAC and MAC OS X 10.6.8 on my MAC Server?

To answer the obvious question. No. None that I've seen. But it may depend on what you mean exactly?
Connecting to file sharing service - None that I've seen
Connecting to Open Directory (assuming proper configuration) - None that I've seen
Using the Server's Mail Service (assuming proper configuration) - None that I've seen
I can say the same about anything else the Server may or may not be offering.

...that makes sense to me.
but, why do so many MBA users (on this forum and others) claim that ventilation occurs through the keyboard? Is this claim based on an old macbook design?

A common misconception of unknown origin. The intake and the exhaust for the cooling fan on the 13" MB and MBP are both located on the rear slot at the base of the hinge. In fact, you can actually see the divider that separates the intake flow from the output flow. If it were through the keyboard crevices, then an awful lot of overheats would result from people using impermeable keyboard covers, as well as Apple's warranty department would be flipping out over the Apple store carrying such covers. iSkin ProTouch FX Keyboard Cover for all MacBooks - Black Printed Keys on White - Apple Store (U.S.)
Does one think that Apple sells these only for use when the Notebook is off??? http://store.apple.com/us/product/TW...co=MTM3OTUwMDE Closing the lid, whilst operating the unit actually results in cooler operation due to reduction in power consumed by operating the display, which in supporting the on-board display generates heat far greater than simply powering the video port..

Re: Is it safe to use MBP with screen lid closed? Leave charge on always?
once again, I've tried a few of these keyboard covers. the Moshi keyboard cover is the ONLY one I can recommend. the others are too thick or change the keyboard experience too much.

1. Closing the cover will cause more heat. This is not because of covering the keyboard very much (though it does help some heat be retained). It's mainly because of the shape of the hinge and the fact when closed it covers up the back vent a lot more. For the best cooling, it is best to have the screen open. Just run it as a dual monitor, but make the external the Primary monitor, and if you don't want to use the built in, just turn its backlight off and don't use it.
2. The thing you plug into the wall is not a battery charger. The actual "charger" is built into the computer. It knows when to charge and when not to. If the little light on the power plug is amber, then its charging your battery. When its green, its just powering the laptop and NOT charging your battery at all.

I'd leave the lid open, at least partially...yes it may be fine not doing that, but you are making heat dissipate worse, of course could even theoretically hurt the screen.
As for the battery...well there's really only two choices, have it plugged in or not. As others mentioned, you can't overcharge the battery. It can be damaged a bit from heat, but of course the number one thing that's going to damage it is discharging it...so it's a no brainer-use it plugged in whenever possible, and try to charge it whenever possible when it's not plugged in.

Nope. Apple would disagree with you on that one. Any "closure", which is, when compared to the amount of CFM, is insignificant. In fact, the opening size remains the same. it is only deflected at a slight angle when the lid is closed. Tilt your MBP and see. As well, shutting down the display lowers the heat being generated, even in the lower case. As I said, if it were a problem, Apple would not be selling stands designed to operate your unit in the closed position as the original poster of this thread proposes to do.

Are there any known issues with Adobe Edge Animate and Yosemite? Experiencing performance issues since upgrading OS

Are there any known issues with Adobe Edge Animate and Yosemite? Experiencing performance issues since upgrading OS. Animation I was working on that had been performing in browser fine suddenly stopped working, and was not related to any action I had done at that point. Also was working in it today and program stopped responding to key board short cut commands.

I am having a whole slew of odd interface problems with a fresh 2014.1.1 on a fresh macbook pro with latest Yosemite. Program locks up, cursor selections don't show, things disappear. I have a mac mini also and the program runs fine on it. Is there possibly something related to the solid state hard drive in new macs?

Is Quark V8.5.1 compatible with OS Lion? Are there any other issues that anyone knows about?

I have a Mac running 10.6.8 and would like to upgrade to Mac OS Lion 10.7.2. Are there any compatibility issues with Quark 8.5.1, Adobe CS5 etc.?

Quark XPress (version 8.5.1)
ISSUE: tools in the tools panel are invisible
current operating system: 10.7.3
It is growing progressively hard to continue to use Quark XPress
I am finding that they are having a very difficult time keeping up with
updates and price points with Adobe and Apple.
I had to purchase this software called Markzware so that I could convert the Quark file to InDesign.
It was not cheap but it was no where near the cost to update Quark to version 9
I like Quark and have to use it for some clients, but the issues are starting to catch up with me now.
If anyone knows how to fix this issue... I WOULD LOVE TO FIND OUT!!!

Are there any known issues when using PSE 13 after installing Apple's recent 10.10.3 Combo update for Yosemite?

I've had Yosemite for some time and bought/installed PSE 13 afterwards.
In the last few days I upgraded to Yosemite 10.10.3.
As a PSE 13 novice I've been working my way through "Adobe Photoshop Elements 13 - Classroom in a Book". Working through the exercises I've found my iMac is sometimes taking longer to process the functions I'm using than prior ro the 10.10.3 upgrade. E.g., using the Healing Brush tools, Straighten Tool etc.
I've struggled with Apple's upgrade and had to re-install my machine from a previous Time Machine Backup and so I was wondering:-
Are there any known issues with PSE 13 post 10.10.3 upgrade?
Are there things I should be concerned about in the future before accepting an OS X upgrade?
Thanks,
Andy

No, no known issues. However it's a good idea to always delete preferences after OS X system updates.
