换个大点的ssd是王道。创见（Transcend）推出了更新套件，如果觉得麻烦也可以加个他们出的特制sd卡，只有一半大小，插进去不突出，缺点就是速度稍慢，可以用来存放文档数据。jd搜下就能看到。
推荐Disk Inventory X和CleanMyMac，前者清理自己创建的大文件，后者清理系统和应用的临时文件
你确定要删除吗 见这个

Sometimes the "Other" category in the About This Mac window may seem large. About This Mac uses this category to count any files that aren't recognized as one of the other listed file types (audio, movie, photos, apps, backups). Examples of files that may be calculated as "other" include:
Items in the OS X folders such as the System folder and caches
Personal information such as documents, contacts, calendar data
App Plugins or extensions
Media files that cannot be classified by Spotlight as a media file because they are located inside of a package
File types not recognized by Spotlight
