how do I know if my computer has an optical drive?

An optical drive is a CD or DVD drive. They are standard on all MacBook Pros and most other Macs released in the last ~15 years.

If your computer is from the past 10 years, it is very, very likely that it has at least USB 2.

How do I know if my computer has a SuperDrive?

I am trying to use IDVD but it wont appear at all and then it said you needed a SuperDrive so I don't know if my computer has one?

Click the Apple icon in the menu bar and choose 'About this Mac'. Click the 'More Info...' button.
In the sidebar or the pane which opens, click 'Disc Burning' (expand thue 'Hardware' list if necessary to see it) and in the list you will see 'DVD write' and the types it can burn: if it doesn't have this you don't have a superdrive (unlikely, I would have thought, they've been standard for some years).
If you need to follow this up please ask in the forum for your model of computer: this forum is for the creation of podcasts.

How do I know if my computer has a virus?

Hello,
When I am on netflix and click on certain buttons more windows open on my computer. It didn't used to happen so I am worried that my computer has been attacked by a virus. How do I know if it is a real virus?
Thanks!

You may have installed one of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates
if it's not already checked.

How do I know If my computer has been hacked?

I think my Mac just got hacked into. I was working on a doc. that had personnel information- names. Phone #s and my home street address. my mac book pro froze up and when it unfroze, all of the names, phone#s and my address changed to ?/-\|# After I stared at the screen w disbelief for less than 1 sec. Word closed it down. After 2 min. Word brought the 2 word doc. I was working on back onto the screen. I looked at the personnel info, and saw the names, phone numbers and my street address in numbers and words. It looked like as if nobody touched my Mac. What should I do? I need help badly. If my computer has been hacked, the information they took, can they steal identity, credit card #s with just phone #s and first&last names besides my street address. I havent touched my computer since thus happened. I'm my iPhone. Should I turn off my computer? Also ididnt save the doc. I was working on. a box came up and said "this file is read-only. To save a copy, click OK and give the document a new namein the Save dialog box( AutoRecovery save of document1)". What should I do? I'm not making this up. I watched everything without realizing what happened. Should I have turned my computer off while it was in the middle of the proscess? Help! Help!

You have not been hacked. Something went wrong with Word and it crashed, and something must have reopened Word. (The system will usually ask if you want to reopen a crashed app... did you see such a message?) Word must have simply reopened the docs you had open when it crashed.
It's actually quite difficult to hack a Mac, and pretty much requires you to help out by opening it up for potential access by hackers.

How do I know if my computer has been hacked into?

I am having two issues with my iMac. One is with my wireless -- in the past few days I've received a few times an IP address error, which seems to be solved by renewing the DHCP lease and restarting. Also, at the login screen when I restart, it takes two tries to log in -- on the first one, my password only partially registers and the screen "bounces", then the second try works. Could this mean that my computer has been compromised? We had some workmen alone in our flat while we were away recently, so there are a few people who've had access to the physical machine as well. Thanks for any help.

How do I know if the program has been downloaded to another computer or not?

How do I know if the program has been downloaded to another computer or not? Also how do I know if it is the educational version or not?

What exactly? Your questions don't make much sense since you failed to provide an explanation what problem you actually have, what program you actually mean and so on. That aside, edu versions are technically not different from the normal programs, just their licensing is different.

How do I know whether my computer supports hd?

How do I know whether my computer (13" MacBook Pro, purchased in 2010) will allow me to play hd movies downloaded from iTunes, or whether I need to download sp versions?

It will play them. Even my 2008 MB plays them perfectly.

How do you know if your computer is running 64 Bit?

How do you know if your computer is running 64 Bit?

That's actually a kind of complicated question. Strictly speaking, there's no such thing as "running 64-bit".
That aside, Intel Core 2 Duo processors and late-model Xeons all have chips that have the Intel EM64T instructions set (64-bit extensions developed by AMD and later adopted by Intel), so they are capable or executing those added 64-bit instructions.
In the Leopard OS, most of the system software has been compiled to make use of 64-bit libraries, but at the same time, 32-bit versions are included for compatibility with pre-Leopard software. So, at any given time you can have software running that uses only the 32-bit instructions, or uses the 64-bit instructions.
Now, albeit the 64-bit libraries are capable of addressing a 64-bit address space, until recently, iMacs and Mac notebooks used Intel chipsets (not the CPU, but the chips that connect the CPU to the other parts of the computer) couldn't address more than the 32-bit address space (a portion of which was reserved, which is why you couldn't use more than 3G of RAM in those Macs).
So, based on that you can ask these questions to see if you are running in 64-bits:
Is the computer a G5 Power PC, Xeon, or Core 2 Duo CPU? If no, you are 32-bit, else go on...
Are you using OS X 10.5 or later? If no, you are 32-bit, else go on...
Does the application "require OS X 10.5 or later" or does it advertise that it's a "64-bit" application? If no, the application is probably 32-bit.
On OS X 10.5 and later, most of the pre-installed Apple-branded software uses the 64-bit versions of the libraries, so they can be said to be "64-bit".

HT5228 How can I tell if my computer has been infected with the Trojan?

How can I tell if my computer has been infected with this latest Trojan (or with any Trojan)? I did install the latest update to Java when I was told by my iMac that new software was available for my computer, which was just 2 or 3 days ago (first week of April). Now it is being said that there was a Java Trojan.
Many thanks for any replies!

Log out and log back in, if you haven’t done so recently. Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
launchctl getenv DYLD_INSERT_LIBRARIES
Post the lines of output, if any, that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line (triple-click anywhere in it to select the whole line):
find /Applications /System/Library/CoreServices -type d -name *.app -exec defaults read {}/Contents/Info LSEnvironment \; 2> /dev/null | grep DYLD_INSERT_LIBRARIES
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
If you get no output from either step, you're not infected with any variant of Flashback that I know of.

How I can know if a user has the permission to read a file or not ?

Hello,
I have other question :
How I can know if a user has the permission to read a file or not ?
Smaine
ThanK's

I don't think common operating systems have an easy way to do that check.
If you have a limited number of files, implement access control yourself, instead of using operating system permissions. E.g. write a configuration file that contains:
# Syntax: "filename": "list of users who can access that file"
somefile.txt: fred, alice, bob
somedir/anotherfile.txt: bob, joe
Read in the configuration file and check against it when a file is being requested.

How do I know if my CPU has decreased speed or what speed my cpu is running?

I recently noticed that when running PRO app my MBP seems pretty slow unusually. I have met this occasion before . I heard that when temperture is too high , the CPU will decrease its speed to protect itself. How do I know if my CPU has decreased speed or what speed my cpu is running?
Thank you!

Enter in the search field of Google 'CPU speed monitors' and you should get some results.

How do I know if my Mac has been infected with the virus

I recently was asked to download an Adobe Acrobat reader update but before I was made aware that the current virus was contained in a similar request, I downloaded what I assumed to be a legit update. I currently do not use my mail program on my Mac so am unaware of any spam being distributed from the computer. How can I identify if my computer has been infected with this Trojan Horse virus?

Two Helpful Links Regarding Flashback Trojan
A link to a great User Tip about the trojan: Flashback Trojan User Tip
A related link in the tip to a checker: Malware Checker Dowload Link
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started.
For now I recommend the User Tip from etressoft to detect and remove:

How do i know if my apple has a virus?

How do I know if my apple has a virus? How do I check?

What makes you ask? Are you having a problem that you believe is due to some kind of malware? If so, what is that problem? Describe the symptoms in detail... they're probably not due to malware, so knowing what is going on is important.
If you're just curious about protecting yourself against malware, see my Mac Malware Guide.
