If your startup disk is full, you may experience issues with software applications running incorrectly or crashing. If you are currently running, the first thing to do is free up disk space. Empty the trash. Look for files you can remove from your Downloads folder (in your home folder). If you use iPhoto or iMovie, emptying the trash in those applications can often free up significant space. Once you have some breathing room, try to find where your space is being consumed. If you have lots of music or pictures or similar items, maybe it's time for some house cleaning to get rid of things you've downloaded or saved but don't really need. How about those applications you downloaded but don't use? If there's nothing you can part with, it may be time for a hard drive upgrade. The good news is this is much easier to do in Mac OS X than Windows because you can migrate all of your user data automatically. If you buy an external USB and/or FireWire case, you can put your old hard drive in that case and use it as a portable or backup drive (ideal for Time Machine) once you've migrated your data to the new hard drive. Depending on your Mac model, you may be able to keep the old hard drive and just add a new hard drive for additional storage. Look for instructions on upgrading your hard drive specific to your Mac model. 1TB hard drives can be purchased for approximately $100 and external cases can be found for as little as $20 for decent models (more for models that offer multiple interfaces or accommodate more than one hard drive).
I would suggest to download free Mac cleaner software like Stellar Speed up Mac to clean OS X startup drive. it will delete junk files from OS X drive and gain free spaces.
press on startup to display the bootable disks.
The fix could be that you are using the wrong startup disk. When you turn your PC or mac on press f1 repeatedly until you come to the startup menu. From this select 'startup' preferences, start up disk and select the right one. If you are unsure there is no harm in trying them all as i doubt you will have more than 2 hard disks.
Restart your computer, then hold the Option (Alt) key as it starts up. Or, use the Startup Disk control panel in Windows or Mac OS X Startup Disk preferences to set the default operating system to use each time the computer starts up.
Go to "System Preferences", then select "Sartup Disk" in "System" section. You gonna see the list of all available partitions for booting. Select the partition you want.
Built into Mac OS X is an application called Disk Utility, which can format and partition any internal or external volume. It's located in /Applications/Utilities/. Additionally, there are some third-party utilities that can work with partitions on-the-fly: iPartition, DiskWorks, and VolumeWorks all claim to do this.
To select which partition the Mac boots from hold down the Option key (alt) when you start up. In System Preferences select Startup Disk and then select the system you want to set as the default startup.
If you want to find information about your mac go into the apple menu (apple icon in the toolbar on top) and click on "about this mac" and it should have your basic mac info like what version you're using, your processor, memory and startup disk. Hope this helped
Reboot means to restart. To restart or reboot click the apple icon top left and then click Restart.
What do you mean?If your mac is loading slow on startup, it is most likelyto do with its SSD; so I'd recommend getting that checked out, or clearing up some space :)
The Mac's Startup Chime tells you that your Mac is working properly. If it changes to some other sound then there is a problem with your Mac. You can press the mute sound key before you shutdown the Mac then it will startup still muted or there are a several pieces of software, such as Psst (see link below), that will silence the chime for you.
Not for the Mac but you can have the Windows 98 Hardware Disk installed on a Mac then download MapleStory.
A Mac can be booted from an external drive. Holding down the Alt/Option key as the Mac starts up will show all the available drives allowing the desired drive to be selected. This can also be set in the Startup Disk section of the System Preferences.
